This film doesn't receive a lot of attention. I grew up a fan of classic film, and I only saw this one once until tonight. Seeing it for the second time (I can't imagine there are any other major-release MM films I haven't seen over & over) I was extremely impressed by the quality of the performance Marilyn turned in. Hardcore fans seem to generally feel that her performance in "the Misfits" is her finest; the role had more depth than many she played, and seemed highly personal. I argue that she does just as fine a job in just as deep a role in "Don't Bother To Knock." It's my belief that MM was _ALWAYS_ versatile and talented, but that the American public fell so deeply in love with the breathless (& brainless) beauty role, that the studios typecast her until they weren't sure her looks alone would be enough to guarantee the volume of gross profits which they expected from Marilyn's films.
