A genre of movie that is known to have a very devoted fan base, there is something about sci-fi films that engender a great deal of passion in a lot of viewers. With that in mind, it should come as no surprise that some pieces of movie memorabilia related to sci-fi are in extremely high demand.

Often times based in some kind of crazy world or featuring futuristic items, sci-fi films tend to have amazing and memorable props at the center of their stories. For that reason, there are many wealthy moviegoers that have developed connections to these pieces and are more than happy to pay a pretty penny to own the actual item used in the film. As a result, prices have been driven so high that they’ve inspired this list of 20 pieces of sci-fi movie memorabilia that are worth a fortune.

In order for a piece of memorabilia to be considered for possible inclusion on this list, it first and foremost needs to be related to a sci-fi film of some sort. As such, you could find movie props, particularly remarkable pieces of merchandise, or any other piece that is rare enough that owning it could be the feather in the cap of a film fan. As far as what we are quantifying as being a sci-fi film, obviously that includes the typical kind of movie that falls under that category. That said, on top of that, we looked at films with futuristic elements like crazy gadgets. It should also be noted that items related to fantasy films were not in the running for this list.

Jurassic Park – Velociraptor Cage

Via YouTube.com

A film that took theatres by storm and continues to receive sequels to this day, Jurassic Park did such a good job of telling a story and bringing dinosaurs to life that it became a sensation. Sometimes forgotten by some people that focus on scenes featuring the T Rex or Jeff Goldblum laying on his side with his shirt open, the movie starts on a scary note.

Showing audiences a failed attempt to get a velociraptor into a cage, the sights and sounds make sure that viewers fear them right from the start.

The prop that made that moment possible, that cage with a raptor prop inside of it sold on eBay in 2014 for $99,300.

Alien – Original Alien Suit

Via space.ca

One of the most fearsome creatures ever seen on the big screen, there is something about the Xenomorphs that freaks out a lot of viewers in the best ways possible. Mindless predators that never stop seeking out their prey, they were perfectly crafted to make them look like their efforts to consume their targets are impossible to stop.

Visually designed by the Swiss artist H.R Giger, to say he did a marvelous job in creating a nightmare creature that would haunt audiences for decades would be an understatement.

First seen on screen in the original Alien movie, the suit worn to bring the Xenomorph to life in that film sold at auction for $126,500 in 2007.

Ghostbusters 2 – Proton Pack

via dailygrindhouse.com

A franchise that seems to be hugely important to an entire generation of people, Ghostbusters is the kind of movie that you’ve seen many times but still watch in full when you catch it on TV. While Ghostbusters 2 failed to live up to the high bar left behind by the original film, there is still no doubt that it has many devotees to say the least.

The item that has always been most associated with the series, the proton packs worn by the titular heroes mean so much that many people have created homemade recreations of them.

As cool as it would be to have one of those, they pale in comparison to the ones used onscreen in the second film, one of which sold at auction for $130,000.

The Day the Earth Stood Still – Gort’s Head

via pinterest

One of the best movies about aliens visiting Earth ever made, The Day the Earth Stood Still feels highly relatable more than 60 years after its release. Starring a humanoid being that is looking for a peaceful visit, once a nervous soldier fires upon him it results in the arrival of Gort, an 8-foot tall robot that destroys several human weapons.

Only the opening moments of a thought-provoking film, it speaks to the tribal nature of many people and our suspicion of those that we see as outsiders no matter their intentions.

Still relevant today, sadly, Gort remains its best-remembered figure which is why one of the robot’s surviving prop heads sold for $150,000 in 2012.

The Force Awakens – Han Solo’s Jacket

Via time.com

The first Star Wars movie of the Disney era, The Force Awakens may have had its detractors but for a lot of people, it was a much needed return to form for the franchise. Featuring the return of several beloved characters, including Leia, Chewbacca, C-3PO, and others, they were a sight for sore eyes. Without a doubt, the most anticipated of them all, seeing Han Solo back in the saddle again had seemed like a long shot prior to that. Still possessing all the swagger we’d come to know him for, his leather jacket in the new film played a small role in which helped sell one of the jackets used in the film for $191,000.

King Kong – Original 1933 Metal Model 

Via dailydetroit.com

Far more interesting than most creature features that were released in the same era since then, 1933’s King Kong is still a masterpiece. Unlike many of its competitors, because it featured a giant animal as the misunderstood protagonist of the film, it also wasn’t afraid to have things end up on a sad note for the titular ape.

Created through the use of stop-motion animation, a painstaking process that took a great deal of time and discipline, some may see its effects as dated, but when you think about it, they are amazing.

Captured on film by meticulously moving a model, King Kong was made up of a metal skeleton covered in cotton, rubber, liquid latex, and rabbit fur. The only surviving part of the original model, the skeleton sold for $200,000 in 2009.

Aliens - Colonial Marines Dropship

Via propstore.com

One of a select few sequels that were completely different than its predecessor but still successful, Alien was a suspense thriller, but Aliens was much more action packed. Expanding on the world seen in the previous movie in a number of ways, a lot of people focus on the seemingly endless array of Xenomorphs in the movie, but there is a lot more going on than that. Introducing much more of a focus on a military culture, several all-new characters and accessories were seen for the first time. The craft used to take the team of soldiers to tackle the Xenomorph problem on an alien world, the Colonial Marines Dropship looked functional but also was heavily armed. Pretty cool looking, one of the models used to bring the craft to life sold at auction in 2012 for $225,000.

Star Wars - Luke Skywalker’s Lightsaber

via GeekTyrant

A tool that we never really saw Luke Skywalker take full advantage of in the first Star Wars movie, the practice he got with his new lightsaber still played a pivotal part in the movie’s story. After all, it was the understanding of the force he received while being shown the ropes by Obi-Wan on the Millennium Falcon that allowed him to tap into again later in the film. Without that ability, it seems clear that he likely would have failed in firing the shot that blew up the Death Star. With that in mind, and the fact that lightsabers are awesome, it should come as no surprise that one of the props used as Luke’s lightsaber in the movie sold at auction for $240,000.

The Empire Strikes Back and Return of the Jedi – Han Solo’s Blaster

Via starwars.com

From one screen used Star Wars weapon to another, this time around it is time to look at the blaster that Han Solo wielded at various points in the series. Far from as slick as any of the lightsabers that the Jedis used, it could be argued that Han’s blaster was nothing more than an everyday gun aside from the fact that it didn’t shoot bullets. However, since it was the accessory of choice of the most popular Star Wars character it stood out enough that people really grew to care about it. The ultimate piece of movie memorabilia if you want to pretend to be a rogue like Han, someone paid $246,000 to have one of his prop blasters in their collection.

Blade Runner - Rick Deckard’s Tool 

Via time.com

One of a long list of sci-fi films that take place in a dystopian future, somehow Blade Runner managed to still be a gorgeous movie even though it was incredibly dark. A visual masterpiece that is all in service of a story for the ages, audiences hearts were ripped apart for virtually every character that appeared onscreen, even though some of them seem like villains at first. Featuring a cast that is led by Hollywood legend Harrison Ford, the movie features several action scenes but at the end of the day, it is the quiet moments that work best. For that reason, it seems like Rick Deckard’s Pistol would not be the most valuable prop from the film but it sold for $270,000 at auction in 2012 which is hard to beat.

Star Wars and The Empire Strikes Back - Imperial Stormtrooper Costume

via YouTube

Perhaps not the kind of thing that some people would pay a fortune for, considering many Imperial Stormtrooper costumes were made you may expect several to have survived. While there is some truth to that, as there are several individual pieces from Stormtrooper costumes that have sold for a pretty penny, none of them have survived fully intact as far as we know. Considered the closest thing to that, the Stormtrooper costume that sold at auction for $319,574 in 2011 had suffered some minor damage but had also been restored.

2001: Space Odyssey Aries 1B Trans-Lunar Space Shuttle

Via superstarfloraluk.com

One of the most respected filmmakers to ever live, stories of how meticulously Stanley Kubrick would plan everything that appears onscreen in his films are the thing of legend. Most likely the most ambitious project he ever worked on, 2001: A Space Odyssey’s story took audiences from the dawn of mankind to the future.

Featuring several scenes that take place in outer space, the Aries 1B Trans-Lunar Space Shuttle was created for the movie and has gone down in history ever since.

Sold at auction to The Academy of Motion Picture Arts and Sciences in 2015, they payed $344,000 to buy the model of the movie’s legendary shuttle.

Star Wars - Rebel Blockade Runner Spacecraft

Via starships-of-the-universe.com

The ship that introduced the world to the Star Wars universe, when a Rebel Blockade Runner Spacecraft came onscreen in the opening seconds of the first film people were blown away. However, that feeling of astonishment was quickly overshadowed when a much larger Imperial craft slowly came into frame and viewers realized the smaller ship was in great peril.

A perfect way of visually showing how outmatched the Rebellion was, it provided scope and allowed audiences to root for the scrappy heroes right from the start.

The model that allowed this entire sequence to take place, one of the props used to bring the Rebel Blockade Runner Spacecraft to life sold at auction for $465,000 in 2015.

Terminator 2: Judgment Day - Harley-Davidson Fat Boy

via Visordown

The second James Cameron sequel to make this list, when Terminator 2: Judgment Day was first released there were huge expectations. Actually able to exceed them all, the decision to make one of Arnold Schwarzenegger’s T-800 into a hero after the one seen in the previous film was so scary was ingenious. First seen in the film without a single stitch of clothing on, the T-800 quickly makes his way to a biker bar where he takes the clothes and motorcycle of someone against his will. First sitting on the Harley-Davidson Fat Boy in an amazing moment, he also rides the bike in a chase scene from the movie that is among the best ever put on film. A fully functioning motorcycle and part of movie history, the bike seen in the movie sold at auction for $480,000.

Terminator 2: Judgment Day –T-800

via YouTube

A film that almost all sci-fi films have seen multiple times, they should all know that throughout the movie's runtime many T-800s are seen on screen in future scenes. However, what they may not have learned is that only one of the models used to bring them to life was crafted with metal feet attached for various reasons. Obviously more valuable since it is one of a kind and linked to a movie that has passed the test of time, that T-800 was sold at auction and managed to bring in $488,750 for its owner.

Metropolis – Original Poster

Via potentialfilms.com

Considered by many people to be the best sci-fi movie from the early years of filmmaking, Metropolis came out in 1927, but is still studied around the world to this day. All the more amazing given the fact that the original version of it has been lost for decades, it has been restored several times which has led to at least 9 different cuts of it existing. The best remembered element of the movie, Metropolis’ machine man is still one of the most recognizable robots ever seen on the big screen. More than 90 years old at this point, it is simply amazing that a print of one of the posters originally used to promote Metropolis continues to be in decent shape. For that reason, one of them sold for $690,000 in 2005.

Back to the Future Trilogy – DeLorean

Via collider.com

An amalgamation of many different film genres, the Back to the Future trilogy are sci-fi classics that can also be described as comedies and family films. Featuring one of the most lovable cinematic pairs in history, watching Doc Brown and Marty McFly team up is so much fun that many viewers can’t get enough of them.

A series of stories that were all made possible because Doc made a time machine out of a DeLorean, for many people, they’ve become the best movie car in history.

Clearly one of the people that feels that way, someone bought one of the DeLoreans used to film the trilogy at auction for $541,000 in 2011.

The Spy Who Loved Me – Lotus Submarine Car

Via usatoday.com

A movie that may seem somewhat out of place on this list, in a lot of ways The Spy Who Loved Me has nothing in common with something like Star Wars. However, given that it features gadgets that had no real basis in reality at the time of its release, at the very least it had sci-fi related elements. Probably its best piece of technology, creating a submarine car was possible, but nothing like the one seen in this movie has been crafted yet. One of six submarine cars created out of the body of Esprits for the movie, this piece of memorabilia was in a storage locker that a lucky person bought the contents of for $100. Completely unaware of what was inside, he had it fully restored and eventually sold it for $860,000.

Batman: The Movie – Batmobile

Via redbull.com

A vehicle that has been reimagined over and over again, the Batmobile has gone through many iterations in the past, just like many actors have played the caped crusader. Still one of the most memorable all these years later, the one that Adam West rode in during the 1966 TV show is fondly remembered. Of course, this list is related to movies only, which means that we couldn’t feature the original Batmobile here if it hadn’t been seen in the film adaptation of the show, Batman: The Movie. Still a beloved movie car, when one of the 1966 Batmobiles sold at auction in 2013 it bagged the amazing figure of $4,600,000.

Forbidden Planet – Robby the Robot

Via YouTube.com

Considered by many observers to be one of the best sci-fi films of the '50s, even with that in mind, most people would have bet against a piece related to Forbidden Planet taking the top spot on this list. Yet, here we are and when you think about it there is a certain logic to it that makes perfect sense. The kind of prop that you wouldn’t have expected to have survived this long intact, it seems like somebody would have broken off pieces of it or something like that. However, a “fully functional” version of Robby the Robot from Forbidden Planet was auctioned off in 2017 for the ridiculous amount of $5,375,000.
