River of No Return

River of No Return is a 1954 American Western musical film directed by Otto Preminger and starring Robert Mitchum and Marilyn Monroe. The screenplay by Frank Fenton is based on a story by Louis Lantz, who borrowed his premise from the 1948 Italian film Bicycle Thieves. The picture was shot on location in the Canadian Rockies in Technicolor and CinemaScope and released by 20th Century Fox. This is as well the first film in which the CinemaScope extension to the 20th Century Fox fanfare was used.
