Three On A Couch (1966)

An artist (Jerry Lewis, who also directs) gets offered a prestigious commission in Paris and wants his fiancee (Janet Leigh) to come with him so they can be married in Paris. But she's a psychiatrist and reluctant to go because of three female patients (Mary Ann Mobley, Leslie Parrish, Gila Golan) who are having hostile feelings toward men. So the artist takes it upon himself to impersonate the ideal man to each of the women. Of course, this is bound to backfire. With Lewis at the helm, one would think this should be a sure fire farce but it mostly misses. It's not so much the script as most of the players aren't as adept in farcical comedy as they should be. Notably James Best (who curiously gets "and introducing" billing after being in films for 16 years and over 40 movies) as Lewis' best friend who doesn't appear to have a comic bone in his body. There are a couple of laugh out loud sight gags and one genuinely hilarious sequence with Lewis playing both a Southern matron and her nerdy brother that puts the rest of the movie to shame. With Kathleen Freeman and Fritz Feld.
