Marilyn Monroe (born Norma Jeane Mortenson; June 1, 1926 – August 5, 1962) was an American actress, model, and singer. Famous for playing comic "blonde bombshell" characters, she became one of the most popular sex symbols of the 1950s and was emblematic of the era's attitudes towards sexuality.

"Dangerous Years" is a 1947 American drama film produced by Sol M. Wurtzel, directed by Arthur Pierson, starring Billy Halop and Ann E. Todd. Marilyn Monroe makes her first on screen appearance as Evie the waitress in the restaurant scene. Her voice previously appeared in the film "The Shocking Miss Pilgrim", which was released months earlier.

Monroe had no film roles during the first months of her contract and instead dedicated her days to acting, singing and dancing classes. Eager to learn more about the film industry and in order to promote herself, she spent time at the studio lot to observe others working. Her contract was renewed in February 1947, and she was given her first two film roles, bit parts in "Dangerous Years" (1947) and "Scudda Hoo! Scudda Hay!" (1948). The studio also enrolled her in the Actors' Laboratory Theatre, an acting school teaching the techniques of the Group Theatre; she later stated that it was "my first taste of what real acting in a real drama could be, and I was hooked". Monroe's contract was not renewed in August 1947, and she returned to modeling while also doing occasional odd jobs at the studio.
