A Millionaire for Christy is a 1951 American comedy film directed by George Marshall and starring Fred MacMurray, Eleanor Parker and Richard Carlson.

The film is a screwball comedy, in which Christy Sloane (Parker) is a legal secretary from San Francisco who is sent to Los Angeles to inform radio host Peter Lockwood (MacMurray) that he has just inherited $2 million.

Christabel "Christy" Sloane (Parker) is a legal secretary in San Francisco whose desire for finer things is at odds with her desperate financial straits, causing her to lament to her coworker Patsy (Una Merkel) that she needs to find a millionaire to marry.

Her boss orders Christy to go to Los Angeles to inform Peter Ulysses Lockwood (MacMurray) of an inheritance of 28,000,000 pesos ($2,000,000) that a deceased uncle has bequeathed him and obtain the necessary legal documents.

Christy arrives on Peter's wedding day as he is scurrying to get dressed for the ceremony and finish packing for a honeymoon cruise to Honolulu with his bride, heiress June Chandler.

Christy "awakens" and acts seductively, but Peter, in reality a notorious ladies' man, believes she is mentally unstable and is unmoved.

The wet and weary couple are found by a group of Mexican railroad workers, who, mistaking them for newlyweds, welcome them into their crew car on a nearby siding.
