15. MARIEL HEMINGWAY

Filmmaker: Woody Allen
At 16, Mariel was cast as Woody Allen’s love interest in the classic 1979 film Manhattan. Although she was among a cast of some of the most talented adult actors ever, Allen’s camera displayed her in a way that made audiences realize why his character fell in love with her in the first place. She made such an impression that she was nominated for the “Best Supporting Actress” Oscar.
