My Little Chickadee (1940)

Comedy greats W.C. Fields and Mae West co-wrote the script for this, their first and only film together, and the result is some hilarious verbal sparring in the guise of a traditional western. The plot has Flowerbelle Lee (West) and Cuthbert J. Twillie (Fields) meeting onboard a train where they undergo a sham wedding and are attacked by Indians. They settle in the town of Dry Gulch, where Cuthbert ends up sheriff as a result of his endless bragging at the poker table. He also bartends at the local saloon, where he tangles with an inebriated Mrs. "Pygmy" Allen (Fay Adler). Flowerbelle meanwhile teaches school, sings "Lily of the Valley," and goes after younger men like Wayne Carter (Dick Foran) and Jeff Badger (Joseph Calleia). When Cuthbert gets mistaken for a masked bandit it's up to Flowerbelle to strap on a pair of six-shooters and ride to his rescue. This might seem like a lot of plot, but the two stars still have plenty of room to breathe, thanks to the relaxed direction of Eddie Cline.
