My Little Chickadee (1940) is a Universal comedy/western motion picture starring Mae West and W. C. Fields, with Joseph Calleia, Ruth Donnelly, Margaret Hamilton, Donald Meek, Willard Robertson, Dick Foran, George Moran, William B. Davidson, and Addison Richards. It was directed by Edward F. Cline. The original music was written by Ben Oakland (song "Willie of the Valley") and Frank Skinner.
West reportedly wrote the original screenplay, with Fields contributing one extended scene set in a bar. Universal decided to give the stars equal screenplay credit, perhaps to avoid the appearance of favoritism, but the move incensed West, who declined to re-team with Fields afterwards. The stars spoofed themselves and the Western genre, with West providing a series of her trademark double entendres.
