Marilyn without the Strasbergs, without the Russian drama coach, without the Method, without the hours locked in her trailer shaking with stage fright. And it is her best ever acting job. This is the ONLY film that really taps into the 'off-kilter' and wounded quality of MM and uses it as an indispensable element of the movie. Elisha Cook's little turn as an elevator operator and his repartee with M.M. is a memorable minor moment and one of many such delights scattered throughout. I've heard that Richard Widmark was very nice to Marilyn and helpful on the set. Of course with 40 or 50 takes for even short scenes, a Billy Wilder can put up on the screen a dazzling Sugar Kane in Some Like It Hot but this is the real Marilyn not just her sheer 'luminescent beauty'. Even by the time she made Niagara, something was lost already, though she was very good in that.
