For me this movie is one of the best movies released in year 1964. Sex and the Single Girl is a 10/10 movie for me. Before you read this review and before I spoil you the story, watch the movie, I highly recommend it. Anyway, Comedy may boast of one of the biggest numbers of good movies. Richard Quine's films play on emotions and are able to move a more sensitive viewer. You can watch the movie online here or download it.
