Helen Slater
This fresh-faced, tall blonde lead literally soared to fame as "Supergirl" (1983). Slater later turned in creditable performances in "The Legend of Billie Jean" (1985), as a youth unjustly accused of murder, and "Ruthless People" (1986), as a ditsy kidnapper. After stalling a bit in such mild fare as "Sticky Fingers" (1988) and "Happy Together" (1989), Slater enjoyed her biggest popular success to date in "City Slickers" (1991) as the one female member of the big cattle drive. Her subsequent feature work was in generally forgettable fare, except for the family film "Lassie" (1994).
