Oklahoma! is a 1955 musical film based on the 1943 stage musical Oklahoma!, written by composer Richard Rodgers, and lyricist/librettist Oscar Hammerstein II and starring Gordon MacRae, Shirley Jones (in her film debut), Rod Steiger, Charlotte Greenwood, Gloria Grahame, Gene Nelson, James Whitmore and Eddie Albert. The production was the only musical directed by Fred Zinnemann. Set in Oklahoma Territory, it tells the story of farm girl Laurey Williams (Jones) and her courtship by two rival suitors, cowboy Curly McLain (MacRae) and the sinister and frightening farmhand Jud Fry (Steiger). A secondary romance concerns Laurey's friend, Ado Annie (Grahame), and cowboy Will Parker (Nelson), who also has an unwilling rival. A background theme is the territory's aspiration for Statehood, and the local conflict between cattlemen and farmers. In 2007, Oklahoma! was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
