A superhero film, superhero movie, or superhero motion picture is a film that is focused on the actions of one or more superheroes; individuals who usually possess superhuman abilities relative to a normal person and are dedicated to protecting the public. These films typically feature action, fantasy and/or science fiction elements, with the first film of a particular character often includes a focus on the origin of the special powers including the first fight against the character's most famous supervillain, or archenemy.
Most superhero movies are based on comic books. By contrast, several films such as the RoboCop series, The Meteor Man, The Incredibles, and Hancock are original for the screen, while The Green Hornet is based primarily on the original radio series and its 1960s television adaptation, and Underdog is based on an animated television series.
Almost immediately after superheroes rose to prominence in comic books, they were adapted into Saturday movie serials aimed at children, starting with Adventures of Captain Marvel (1941). Serials such as Batman (1943), The Phantom (1943), Captain America (1944), and Superman (1948) followed.
