This psychological suspense flick was one of Marilyn's first leading roles and gave the sexy star an opportunity to play a serious dramatic role. Viewers who have never seen the great Monroe in a serious part will be amazed. She really was a very gifted and versatile actress. Sincerely, if you have ever dismissed Monroe as just another pretty face, you should really see this film. If after that you're still not convinced, then rent BUS STOP.
