5. They All Laughed (1981)
The unfortunate star: Audrey Hepburn
By 1981, Audrey Hepburn was already a 33-year veteran in Hollywood, so it's not like she needed to make more movies or prove herself to anyone. Like Robert De Niro in recent years, though, the star of classics like Roman Holiday (1953) and Breakfast at Tiffany's (1961) felt the need to collect another paycheck when she signed onto director Peter Bogdanovich's ensemble comedy They All Laughed.
Better described as "they all suffered," They All Laughed is a wildly uneven screwball flick that can't ever decide if its a romantic affair or a silly, slapstick diversion. And through it all, Hepburn, playing a woman who suspects her husband is being unfaithful, sleepwalks toward the dollar bill at the end of the proverbial tunnel.
