Speed is a 1994 American action thriller film directed by Jan de Bont in his feature film directorial debut. The film stars Keanu Reeves, Dennis Hopper, Sandra Bullock, Joe Morton, and Jeff Daniels.

Released on June 10, 1994, it became critically and commercially successful, grossing $350.4 million on a $30 million budget and winning two Academy Awards, for Best Sound Effects Editing and Best Sound, at the 67th Academy Awards in 1995.
