58. CHER
Mask (1985)

Still revved from her nominated turn in 1983's Silkwood, Cher roared onto screens as Rusty Dennis, a motorcycle mama who cares only about ''getting loaded and laid.'' But, in truth, all her tenacious character really cares about — as reflected in Cher's fierce and complex performance, which may have suffered at Oscar nomination time due to director Peter Bogdanovich's fight with distributor Universal — is protecting her sweet, damaged bond with her sweet, damaged boy.
