Wait Until Dark (1967) is a suspense-thriller film directed by Terence Young and produced by Mel Ferrer. It stars Audrey Hepburn as a young blind woman, Alan Arkin as a violent criminal searching for some drugs, and Richard Crenna as another criminal, supported by Jack Weston, Julie Herrod, and Efrem Zimbalist Jr.. The screenplay by Robert Carrington and Jane-Howard Carrington is based on the stage play of the same name by Frederick Knott.

Hepburn was nominated for the Academy Award for Best Actress (losing to Katharine Hepburn), and Zimbalist was nominated for a Golden Globe in the supporting category. The film is ranked #55 on AFI's 2001 100 Years…100 Thrills list, and its climax is ranked tenth on Bravo's 100 Scariest Movie Moments.

In an effort to duplicate the suspense on screen in the climactic scene, movie theaters dimmed their lights to their legal limits, then turned them off one by one until each light on-screen was shattered, resulting in the theater being plunged into complete darkness.
