The DC Extended Universe (DCEU) is an unofficial term[a] used to refer to an American media franchise and shared universe that is centered on a series of superhero films, distributed by Warner Bros. Pictures and based on characters that appear in American comic books by DC Comics. The shared universe, much like the original DC Universe in comic books and the television programs, was established by crossing over common plot elements, settings, cast, and characters. The films have been in production since 2011 and in that time Warner Bros. has distributed five films. The series has grossed over $3.7 billion at the global box office, currently making it the fourteenth highest-grossing film franchise.
