Batman Movie - 1989

Batman is an American Academy Award-winning superhero film based on the DC Comics character Batman created by Bob Kane and Bill Finger. It is the first entry in the original four-part Batman film series, the first directed by Tim Burton and the first to star Michael Keaton as Bruce Wayne/Batman. It also starred Jack Nicholson as The Joker. Inspired by the original work of Bill Finger and Bob Kane from the late thirties and forties and also by the darker Batman comics of the 1980s (including the work of Frank Miller and Alan Moore), the film moved the franchise toward Batman's dark roots and away from the campy 1960s interpretation of the character. The film also served as an inspiration for Batman: The Animated Series, because of its dark nature. source:
