Premise: Marilyn Monroe ( born Norma Jeane Mortenson ; June 1 , 1926 -- August 5 , 1962 ) was an American actress and model . Over the next two years , she became a popular actress with roles in several comedies , including As Young as You Feel and Monkey Business , and in the dramas Clash by Night and Do n't Bother to Knock . By 1953 , Monroe was one of the most marketable Hollywood stars , with leading roles in three films : the noir Niagara , which focused on her sex appeal , and the comedies Gentlemen Prefer Blondes and How to Marry a Millionaire , which established her star image as a `` dumb blonde '' . The Seven Year Itch is a 1955 American romantic comedy film based on a three-act play with the same name by George Axelrod . In television , film , and theatre , typecasting is the process by which a particular actor becomes strongly identified with a specific character ; one or more particular roles ; or , characters having the same traits or coming from the same social or ethnic groups .
Hypothesis: Marilyn Monroe acted.
