Daryl Hannah
Clan of the Cave Bear (1986)

She was hot as a mermaid (Splash) and an android (Blade Runner), but nothing quite compares to Hannah's turn as a beautiful Cro-Magnon woman living among Neanderthals in this film adaptation of Jean Auel's novel. At least there was something to distract audiences from the movie's laughably bad, grunting ''dialogue.''
