The Seven Year Itch (1955) | COMEDY/ROMANCE | FULL MOVIE

Like many other Manhattan husbands, Richard Sherman sends his wife and son to the country for the summer, while he stays behind to toil. Though reveling in temporary bachelor freedom of lifestyle, he's resolved not to carouse and philander like some others. But his overactive, over-vivid imagination goes into overdrive when a delightfully unconventional, voluptuous blonde moves in upstairs.
