Here, Marilyn was intense, with acting chops few have given her credit for, and her beauty and mannerisms further enhanced her performance. Even her walk was unique and showed her years of hard study and work to become a serious actress. Co-writer and producer, Billy Brackett, collaborated with Billy Wilder on several films with Wilder directing like "Sunset Boulevard," a story of how Hollywood discards talented actresses for youth and beauty's sake. Monroe was no exception to the rule.

A classic staring Monroe

Niagara is an unsung film showcasing Marilyn Monroes acting skills in a dramatic role. Largely overlooked, this film shows Marilyn playing a wife of neurotic returned soldier played by Joseph Cotton. To say more would ruin the film for Monroe fans, watch it, it's an entertaining thriller.
