The Moon is Blue falls into the category of older romantic comedies that now leave us wondering about its initial impact on the film landscape. Nevertheless, it did generate some buzz, and ultimately provides a rather insightful look at social conventions, proper behavior, and attitudes toward relationships. Otto Preminger directed this film, which was adapted from F. Hugh Herbert’s playful stage production of the same name. It features William Holden, David Niven, and Maggie McNamara in the leading roles. The story centers on McNamara maintaining her virginity while facing attention from several men, with the understanding that she will eventually end up with the right person if she remains steadfast. The film can feel a little verbose and occasionally burdened by its theatrical roots, but the humor possesses a sharp quality that keeps you engaged, and the acting combined with Preminger’s skillful camera work makes it worthwhile to watch. It's more of an interesting find than a must-see classic, but it is enjoyable and offers memorable characters. 7/10
