20 Actors Who Went to Crazy Extremes For Their Roles

Every week, the movie box office rakes in tens, if not hundreds of millions of dollars from audiences looking to see the latest films. Away from the theatre, millions of people buy DVDs and Blu-ray discs or stream their films over any number of internet providers. It all makes for a multi-billion dollar-per-year industry. What pulls in audiences and makes them spend vast sums of money to watch a couple hours of on-screen entertainment? In some cases it may just be a nagging significant other who won’t stop until you go and see that new rom-com. Perhaps you’ve heard good things about a particular movie while standing around the office water-cooler. Or, maybe there is an actor whose previous work you’ve really enjoyed and you’d like to see their newest film.

Even today, with all of the reliance on special effects and CGI, the ability of an actor can help make or break a film. Sure, as the Star Wars prequels demonstrated, a healthy fan-base and special effects can help carry an otherwise mediocre film with mediocre acting – but in most instances if the acting is bad or not believable, the film will flop. This is why certain actors in Hollywood (and around the world) control high amounts of respect and matching pay rates. Certain men and women have demonstrated their ability to take a role and make us believe they are a particular character. In turn, our belief in their character helps to better immerse us in the film.

This list focuses on the actor, and specifically those actors which go the extra mile to make their character(s) more believable. Most of the 20 actors listed here are familiar names you’ll recognize immediately. To varying degrees they have all pushed themselves and/or their bodies to extreme limits in order to become their on-screen personality. Insane weight loss and gain, lifestyle changes and physical training are just a few of the ways these actors go to extreme lengths in order to get into character.

20 Demi Moore

Via reelz.com

Perhaps one actor a lot of people overlook when they assess character preparation is Demi Moore. Lately, the 51-year-old hasn’t been in the spotlight as much as she was in the 1990s and early 2000s. Nevertheless, she has shown she can put a lot into preparing for her roles. For the 1996 movie Striptease, Moore became a stripper, complete with all the training and stage moves, and an amazingly in-shape body to match. Then, just one year later, she took on a most un-stripper-like role when cast as Jordan O’Neill in G.I. Jane. Moore shaved her head, got into even more amazing shape and even undertook a variety of intense training which was led by military advisors and SEAL staff.

17 Vincent D’Onofrio

Via blog.ricecracker.net

Let’s stay with Kubrick for a while. If you’ve ever seen Full Metal Jacket then you know it’s really two movies in one. The first is a dark, disturbing and (sometimes) funny look at a marine boot camp during the Vietnam War while the second half of the film looks at the absurdity of war, specifically in Vietnam. While Gunnery Sergeant Hartman steals most of the attention in the first half of the film, it is the progressively disturbing character of Private Pyle, played by Vincent D’Onofrio, which the storyline builds up to. D’Onofrio’s character is supposed to stand out and not fit with the marines around him. He is awkward, goofy, unathletic and slow minded. To help emphasize Pyle’s ‘uniqueness’ D’Onofrio gained 70 lbs for the film over the course of seven months. While it took nine months to get the weight off, D’Onofrio’s overweight character became yet another one of Kubrick’s memorably twisted characters.

16 Tom Cruise

Via jnash7blog.wordpress.com

Say what you will about Tom Cruise’s sometimes strange behavior, but the guy makes some pretty good movies. From Top Gun to The Last Samurai to Mission: Impossible, Cruise’s films have always packed theatres and entertained audiences. The A-list celebrity is also willing to put in a good deal of effort to get into the mindset of the character he is portraying. Case in point – for 2004’s Collateral the 52-year-old actor had to portray a contract killer. In order to get into the role of someone who could blend in with a crowd and go unnoticed, Cruise took on the real-life role of a UPS delivery man. He went about a routine of delivering packages to various people and stores with the goal of remaining unnoticed. This he did successfully, operating in crowds and engaging in conversations while maintaining anonymity.

15 Charlize Theron

Via heyuguys.com

From Devil’s Advocate to A Million Ways to Die in the West, Charlize Theron is one of the most recognizable actors today. It also doesn’t hurt that she is one of the most beautiful, as well. The South African-born star has played a wide variety of roles but surely one of the most challenging was as convicted serial murderer Aileen Wuornos. To say Theron had to tone down her looks for the role would be a massive understatement. The actor gained over 30 lbs and even shaved her eyebrows all to make herself closer to character.

14 Sylvester Stallone

13 Mickey Rourke

Via celebrityfitnesstraining.com

Seriously, look at a picture of Mickey Rourke from the 1980s-90s and look at one from around 2010. That, kids, is why you should be very careful about getting plastic surgery. In all seriousness, Rourke’s facial change was not for any particular movie role but was largely motivated by his desire to ‘reconstruct’ his looks after years of boxing. Facial changes aside, this is one actor who demonstrated he is willing to push that little bit more to get a role just right. This was demonstrated in 2008 when Rourke took on the role of Randy Robinson in the hit The Wrestler. The then 55-year-old had to get into real shape if anyone was going to believe him as a wrestler on screen. Rourke dropped the flab and put on 30lbs of muscle. He also put in considerable hours training and learning to pull off ‘real’ wrestling moves.

12 50 Cent

Via online.wsj.com

Definitely not an actor you’d think would be on this list. That said, while 50 Cent is better known for his music career, Curtis Jackson has appeared in around two dozen projects for films, television shows and video games. One role he definitely went to extreme lengths for was for the 2011 film All Things Fall Apart where he portrays Deon, a football player who ends up battling cancer. Jackson is known to be a large and muscular individual. To look the part of someone being ravaged by cancer, the 39-year-old went on a liquid diet and reportedly ran on a treadmill for at least three hours every day. The end result was that Jackson lost 54 lbs. and looked the part of someone battling a terrible disease.

11 The Cast of Saving Private Ryan

Via ifhopeislost.wordpress.com

When Steven Spielberg’s Saving Private Ryan hit theatres in 1998 it represented a massive change in the way war was portrayed on screen. The film took war movies to a new level by showing battle as a massive arena of noise, chaos, gore, fear and confusion. A big part of the film’s success was that the actors ‘acted’ like soldiers instead of stars dressed up as soldiers. This was accomplished by putting the majority of the cast through a boot camp led by Dale Dye, a former Marine Corps officer who had been in combat in Vietnam. For 10 days, actors like Tom Hanks and Tom Sizemore lived and trained outdoors in all sorts of weather, eating rations and learning how to operate period-accurate weaponry. Interestingly, Matt Damon was not including in the training so as to help with the on-screen ‘barrier’ between Private Ryan and his rescuers when they meet near the end of the film.

10 Tom Hardy

Via batman.wikia.com

If you’ve ever watched Steven Spielberg’s Band of Brothers you’ve probably seen Tom Hardy in his earliest on-screen appearances. He’s the scrawny soldier Janovec who ends up getting killed after the war is over. Hard to believe that same skinny kid became the massive and powerful characters of Charlie Bronson and Bane in around a decade. Now 37 years old, Hardy first pushed his body when he gained 42 lbs to play notorious inmate Charlie Bronson, a prisoner known for his extreme strength and strange behavior – he fought a Rottweiler in a prize fight once. Bronson even shaved off his mustache and sent it to Hardy to wear during the film. In 2012, Hardy bulked up again and put on 30 lbs of muscle to play Bane in The Dark Knight Rises.

9 Jared Leto

Via de.news724.com

Musician-turned actor Jared Leto has enjoyed an acting career dating back to the early 1990s. Notable films include The Thin Red Line, Fight Club, American Psycho and Alexander. Recently, he has received attention for his portrayal of a trans-gender woman with HIV and AIDS in Dallas Buyers Club. For the role, the 42-year-old dropped his weight to just 114 lbs by not eating. It’s not the first time the actor has had to drastically adjust his weight. In 2007, Leto portrayed Mark David Chapman, the man who killed John Lennon. In order to make the character as realistic as possible, Leto gained nearly 70 lbs. by consuming a daily concoction of ice cream, soy sauce and olive oil. Yum.

8 Heath Ledger

Via standupforthetruth.com

When Heath Ledger burst onto the mainstream with A Knight’s Tale and The Patriot in the early 2000s, not many people thought he would develop beyond a pretty-boy heart-throb. Just several years later and the Australian-born actor was starring in such films as Brokeback Mountain and The Dark Knight. Ledger’s acting in Christopher Nolan’s The Dark Knight gained the actor widespread praise. As the Joker, Ledger gave the character a more sinister and psychotic angle than previously portrayed. It was reported that in order to develop the voice and mannerism of Gotham’s homicidal Joker, Ledger had locked himself away in a hotel room for six weeks. Unfortunately, the praise for his performance was posthumous as Ledger died several months before the film was released.

7 Natalie Portman

Via fanpop.com

When we earlier pointed out that Star Wars had some bad acting in it, yes, Natalie Portman was one example. Anyone who has followed her career knows she can be a very good actor, which is why it's so strange that after travelling to a galaxy far, far away, she temporarily displayed the acting ability of a wet piece of cardboard. In any event, Portman is one actor who is definitely willing to go the extra mile for her film roles. In order to play a ballerina in the 2010 film Black Swan, the Israeli-born actor undertook a daily regime which included five hours of ballet, swimming and cross-training. All of this was undertaken while on a daily diet of 1,200 calories.

6 Matthew McConaughey

Via reveremagazine.com

All right, all right. In addition to appearing on numerous magazine covers and in some interesting cologne and car ads, Matthew McConaughey has appeared in a wide variety of films. It all started with Dazed and Confused in 1993 and although he gave us some forgettable films like U-571 and The Wedding Planner he has had some pretty good roles as well. In 2013, the 45-year-old Texan took on the role of Ron Woodroof, an individual afflicted with AIDS who tries to get around the system to get medication for people facing the disease. McConaughey lost around 47 lbs to play the role and you can still tell he hasn’t fully recovered from it.

3 Robert De Niro

Via museumofcinema.com

To say Robert De Niro is a great actor or a film legend would be an understatement - he played Vito Corleone, after all. He’s been in far too many great movies to list here but it’s obvious he prepares well for all of his roles. Perhaps the best example of this was De Niro’s preparation to play Jake LaMotta, an Italian-American boxer. For preparation, De Niro trained to become a boxer with LaMotta inside the ring with him. Needless to say, the actor also had to get in shape and build a physique like a boxer – something he did successfully. He even entered three boxing matches and won two of them, all in the name of getting into character. In addition to getting in shape and becoming a boxer, De Niro also had to gain considerable weight to portray LaMotta in his post-boxing career. This meant packing on 60 lbs., a Hollywood record until Vincent D’Onofrio surpassed it for Kubrick’s Full Metal Jacket.

1 Daniel Day-Lewis

Via oneclickwatch.org

In the world of movies, almost everything the newly knighted (Sir) Daniel Day-Lewis touches turns to gold. From The Last of the Mohicans to There Will Be Blood, Day-Lewis has continually demonstrated why he wins so many awards for his acting. Away from the screen, he's known for spending a lot of time and effort preparing for each role and getting into character. This is perhaps seen best with My Left Foot, a film in which Day-Lewis plays a character afflicted with cerebral palsy. In order to prepare for and maintain his character, the English actor virtually lived in a wheel chair. He even adopted and maintained such a slouched posture that he broke two of his own ribs.
