The fictional superhero Batman, who appears in American comic books published by DC Comics, has appeared in various films since his inception. Created by Bob Kane and Bill Finger, the character first starred in two serial films in the 1940s, Batman and Batman and Robin. The character also appeared in the 1966 film Batman, which was a feature film adaptation of the 1960s Batman TV series starring Adam West and Burt Ward, who also starred in the film. Toward the end of the 1980s, the Warner Bros. studio began producing a series of feature films starring Batman, beginning with the 1989 film Batman, directed by Tim Burton and starring Michael Keaton. Burton and Keaton returned for the 1992 sequel Batman Returns, and in 1995, Joel Schumacher directed Batman Forever with Val Kilmer as Batman. Schumacher also directed the 1997 sequel Batman & Robin, which starred George Clooney. Batman & Robin was poorly received by both critics and fans, leading to the cancellation of Batman Unchained.
Over the course of seven years, Warner Bros. commissioned Darren Aronofsky for an adaptation of Batman: Year One and Wolfgang Petersen for Batman vs. Superman before deciding to reboot the film franchise in 2005 with Batman Begins, directed by Christopher Nolan and starring Christian Bale. Nolan returned to direct two further installments in the trilogy, The Dark Knight in 2008 and The Dark Knight Rises in 2012 with Bale reprising his role in both films. The two sequels both earned over $1 billion worldwide, making Batman the second film franchise (and to date one of only five, the others being Pirates of the Caribbean, the Marvel Cinematic Universe, Transformers and Jurassic Park) to have two of its films earn more than $1 billion worldwide.Ben Affleck became the newest actor to portray Batman in 2016 with Batman v Superman: Dawn of Justice, which began a sequence of DC Comics adaptations that Warner Bros. refers to as the "DC Extended Universe", including Justice League, a crossover film featuring other DC Comics characters, in 2017, and a stand-alone Batman film starring Affleck and directed by Matt Reeves that is set for release in 2018.
