15The X-Men Movies (The Fight For Gay Rights)
You may think the the X-Men movies are just about mutants with superpowers, but they actually have an underlying meaning that was the main reason Ian McKellen AKA Magneto was attracted to star in them.
You see, the fact that mutants are cast out by society for no good reason
is very reflective of gay people in the real world and, as such, the fight for mutant rights represents the real world struggles for gay rights that gay people have fought to gain for many years. A chat with Bryan Singer convinced McKellen of the movie's deeper significance and it makes a lot of sense when you think about it.
