Suddenly is a 1954 American film noir thriller directed by Lewis Allen with a screenplay written by Richard Sale. The drama features Frank Sinatra, Sterling Hayden, James Gleason and Nancy Gates, among others.
The tranquility of a small town is jarred when the U.S. President is scheduled to pass through and a hired assassin takes over the Benson home as a perfect location to ambush the president. The film is in the public domain.
Film critic Carl Mazek makes the case that the "Machiavellian attitude" of John Baron links the picture with the brutal films noir of the 1950s like The Big Night (1951) and Kiss Me Deadly (1955). Moreover, the themes of violence, sense of claustrophobia and despair mark the film as completely amoral, and, as such, Suddenly is quite opposite of non-noir films like The Desperate Hours (1955).
