The step-niece of distinguished cinematographer Haskell Wexler, this attractive blonde came to the fore with her enjoyable performance as a mermaid in Ron Howard's comedy hit, "Splash" (1984). Hannah's striking features have been the cornerstone of her career--she was perfectly cast in a supporting role as a beautiful android in Ridley Scott's "Blade Runner" (1982)--though she has latterly proved herself capable of less glamorous roles, as in "Steel Magnolias" (1989) and "At Play in the Fields of the Lord" (1991). "The Clan of the Cave Bear" (1986), however, was one such experiment which failed all around. Many of Hannah's more recent films, though, while trying to capitalize on her penchant for whimsy, have offered her little but standard leading lady duties ("Crazy People" 1990, "Memoirs of an Invisible Man" 1992).
