Before the Devil Knows You're Dead is a 2007 crime drama film directed by Sidney Lumet, his last feature film before his death in 2011.
The film was written by Kelly Masterson, and stars Philip Seymour Hoffman, Ethan Hawke, Marisa Tomei, and Albert Finney. The title comes from the Irish saying: "May you be in heaven a full half-hour before the devil knows you're dead". The film unfolds non-linearly, repeatedly going back and forth in time, with some scenes shown from various points of view.
The film received critical acclaim, and was selected as one of 2007's ten most influential American films by the American Film Institute at the 2007 AFI Awards.
