This strikingly attractive black English performer made a memorable feature debut playing an enigmatic high-class call girl with a secret or two in Neil Jordan's "Mona Lisa" (1986). As the mysterious love-object of her driver, a short, dull-witted but good-hearted ex-con (Bob Hoskins), Tyson projected what the NEW YORK TIMES hailed as "a magical screen personality . . . beautiful, intelligent and hard as nails." The press hype of the day selected her for future film stardom--but something subsequently went awry with her movie career.
