Lucky Lady (1975)

When three down-on-their-luck losers, Claire (Liza Minnelli), Kibby (Gene Hackman) and Walker (Burt Reynolds), come together in a Mexican border town to start a booze-running operation during the prohibition, egos, enemies and envy collide. But through some mysterious alchemy and a couple of gunfights, the three become immensely successful bootleggers and, even more surprising to them, a fully functioning "ménage a trois" . A throwback to the great screwball comedies of the 1930s, Lucky Lady was written by Willard Huyck & Gloria Katz (American Graffiti) and directed by the great Stanley Donen (Singin' in the Rain).
