Marilyn comes in 3rd, after Orson Welles and Humphrey Bogart, on this list from Screen Junkies. Along with Bette Davis, she is the only woman on the list – and she appeared in All About Eve alongside Davis, as well as Cary Grant (Monkey Business), Groucho Marx (Love Happy), and her idol, Clark Gable, in The Misfits – the last film either completed.
“There were many early Hollywood sex symbols, but Marilyn Monroe brought sexy to a whole new level. Her most famous movies were Niagara (1953), Some Like it Hot (1959) and Seven Year Itch (1955).”
