This one of good natured spoofs on Hollywood that is set in a real studio and has a number of stars appearing as themselves, usually satirizing their screen personalities. Unlike many films of this type the stars don't out stay their welcome, and are sometimes genuinely funny. The movie is no classic (certainly it's no SINGING IN THE RAIN) but it passes the time agreeably enough and leaves the impression , whether true or not, that the cast and crew had a good time making it. The stars; Dennis Morgan, Jack Carson and Doris Day; work well together. Highlights are Dennis Morgan and Doris Day singing a very pleasant duet, Jack Carson doing an impression on Maurice Chevalier and Irving Bacon in a funny sketch as railway station information clerk.
