Long before the “La La Land” and “Moonlight” Best Picture debacle became the biggest gaffe in Oscar history, it was Marisa Tomei who found herself at the center of an Oscar dispute. When Tomei was nominated for Best Supporting Actress for her work as Mona Lisa Vito in “My Cousin Vinny” — a film that came out 25 years ago today — she was up against heavyweights including Vanessa Redgrave and Miranda Richardson. Tomei was a relatively unknown actress at the time, recognized for her role as a spitfire hairdresser from Brooklyn who knows more about cars than almost anyone. None of her fellow.
