Dark City is a 1998 tech noir film directed by Alex Proyas, and starring Rufus Sewell, William Hurt, Kiefer Sutherland, Jennifer Connelly, Richard O'Brien, and Ian Richardson. The screenplay was written by Proyas, Lem Dobbs, and David S. Goyer. In the film, Sewell plays an amnesiac man who, finding himself suspected of murder, attempts to discover his true identity and clear his name while on the run from the police and a mysterious group known as the "Strangers".

Primarily shot at Fox Studios Australia, the film was jointly produced by New Line Cinema and Proyas' production company Mystery Clock Cinema, and distributed by the former for theatrical release. It premiered in the United States on 27 February 1998 and received generally positive critiques, but it was a box-office bomb. Roger Ebert, in particular, supported the film, appreciating its art direction, set design, cinematography, special effects, and imagination, and even recorded an audio commentary for the film's home video release.

The film was nominated for the Hugo Award for Best Dramatic Presentation and six Saturn Awards. Some critics later noted Dark City's similarities to and influence on the Matrix film series, whose first installment came out a year later, and the film is now widely considered a sci-fi cult classic.

Concerned that audiences would not understand the film, New Line asked Proyas to add an explanatory voice-over to the introduction, and he complied. When a director's cut of the film was released in 2008, among the changes was the removal of the opening narration.
