A vivacious, red-haired actress who began her career as a dancer on a Danny Kaye special and now often plays wives and girlfriends, Annette O'Toole began her acting career in earnest with an episode of "Gunsmoke." She made her feature film debut as a savvy beauty contestant in "Smile" (1975) and next was Robby Benson's leading lady in "One on One" (1977), in which he was a misunderstood college student on a basketball scholarship and she gave him the support he needed. O'Toole had a similar role opposite Eric Roberts in "King of the Gypsies" (1978), in which he was a gypsy warring with his family and his background and she was his "American" girlfriend. She has subsequently played Lana Lang, the high school sweetheart of Clark Kent in "Superman III" (1983) and co-starred with Martin Short in "Cross My Heart" (1987).
