Cause for Alarm! is a 1951 film noir suspense film directed by Tay Garnett, written by Mel Dinelli and Tom Lewis, based on a story by Larry Marcus. Ellen (Loretta Young) narrates the tale of "the most terrifying day of my life", how she was taking care of her bedridden husband George Z. Jones (Barry Sullivan) when he suddenly dropped dead. The film is in the public domain.
Francois Truffaut's short overview of Cause for Alarm! was kinder than many when he wrote, "But all those effects hit home, perfectly timed, and isn't that what counts?" 21st century reviews have tended towards Truffaut's take along with citing the film's suburban noir setting.
