In one of his best (and most unheralded) performances, Frank Sinatra plays a pro assassin who joins other killers in the small town of Suddenly, Ca., where he plans to murder the president of the United States. Sinatra and his associates pose as federal agents in order to take a family hostage and use their house as the base for their operations. With Sterling Hayden, James Gleason. Includes both the original black-and-white and the newly colorized versions. 76 min. Standard; Soundtrack: English.
