This is another Martin & Lewis movie I watched on YouTube. Two years after At War with the Army, they're back there although Jerry's only there because Dean needs his old performing partner back to put on a show. Mona Freeman is Lewis' new partner back in New York where they're supposed to prepare for a Broadway show. So Jerry's there under false pretenses and...oh, watch the movie to see how it all turns out. In chronologically reviewing this iconic team's movies, I've mentioned when their leading ladies did another film with them. Now I can say what male co-stars have made return appearances: First, there's Robert Strauss-previously their superior officer in their last picture Sailor Beware-once again as their sergeant who eventually warms up to Lewis. Then there's Don DeFore-previously Dean's rival in My Friend Irma-as one of Dean and Jerry's fellow privates. Since there's a show business angle involved, there's plenty of musical numbers with Dean either by himself with some dancers or with Jerry clowning around. Jerry himself has a number with Ms. Freeman though her singing voice is dubbed by Imogene Lynn. In summary, this was quite hilarious to me with Dean himself, for once, getting almost as equal laughs as Jerry especially during that lunch-on-a-train sequence with Strauss and another actor named Richard Erdman who's character Lewis is impersonating. So on that note, I highly recommend Jumping Jacks.
