Marilyn Monroe is seen performing in a scene from the film “There’s No Business Like Show Business†in 1954. In all, Monroe appeared in 23 motion pictures that grossed about $200 million. Sensual and seductive, but with an air of innocence, Monroe became one of the world’s most adored sex symbols. She died of a barbiturate overdose at age 36, alone in her Hollywood bungalow.
