Is Your Honeymoon Really Necessary? never really answers its own question, but has no difficulty delivering laughs in full measure. U.S. officer Laurie Vining (Bonar Colleano) hopes to spend a romantic honeymoon in London with new bride Gillian (Diana Decker). Unfortunately, Vining's former wife Candy (Diana Dors) flounces into view, claiming that their divorce is invalid. Legal advisor Frank Bettertorn (David Tomlinson) is brought in to straighten things out--only to find himself in a compromising position of his own. Based on a play by E. V. Tidmarsh, Is Your Husband Really Necessary was shot in two different versions: the British print permitted audiences a view of Diana Dors in a skimpy bikini, while the American version covered up her ample frame with a nightie.
