Dark City (1998)

Separated from his wife Emma (Jennifer Connelly), amnesiac John Murdoch (Rufus Sewell) awakens alone in a strange hotel to learn he is wanted for a series of brutal killings - but he can't remember if he did or didn't commit these murders. Indeed, most of his memories have completely vanished, and he becomes the focus of interest for both mad genius Dr. Schreber (Kiefer Sutherland) and sympathetic detective Frank Bumstead (William Hurt).
