Justice League is a 1993 American superhero film, directed and written by George Miller, based upon many characters appearing in comics published by DC Comics. It is a cross-over between Warner Bros.' initial Superman and Batman film series, with Christopher Reeve and Michael Keaton reprising their respective roles of Kal-El/Superman and Bruce Wayne/Batman, as well as John Wesley Shipp reprising his role as Barry Allen/The Flash from the Flash television series. The film introduces the characters of Wonder Woman (Sandra Bullock), Green Lantern (Bill Paxton), and Aquaman (Patrick Swayze).
Lex Luthor, having escaped from prison once more, returns to his secret lab underneath the city of Metropolis where he has the corpse of the Joker, which he stole from a Gotham City morgue. He is able to resurrect the Joker, and tells him that together they can get revenge on Superman and Batman, and take over the world. They break Captain Cold out of prison in Central City, find the insane Catwoman hiding out in the Gotham City rooftops, meet the super-intelligent ape Gorilla Grodd in his sewer lair, and break the Black Manta out of Blackgate Prison. Together, they meet in a special laboratory located in a remote swamp, and Lex tells them that they shall become the Legion of Doom.
