Not only can Marilyn Monroe act, but she is also a very funny lady as well. Quite an ensemble cast, here, with Tom Ewell, as the schizophrenic tenant who lives beneath Marilyn, and his fantasies about what it might be like to have an "affair" with the girl upstairs. Then when he learns that in this particular hot summer, that she doesn't wear underwear, well, his imagination takes off.
There are some great scenes, but many of them deal with the outrageous scenes which Ewell imagines, with one of the best being his playing the piano like Sergei Rachmaninoff, while Marilyn sits next to him on the piano bench, and when the real scene develops, we find he can only play "Chopsticks" and the real scene is so far removed from his imagined one.
He's a strange one, this man, and Marilyn plays well in this movie. It's unfortunate that she was so under-rated!!
A great comedy, and it's highly recommended!!
