From the rollicking opening of the camaraderie of a returning U.S. submarine crew to the booming "Great Guns" of the movie's finale, it's easy to understand why this movie was an antidote to the Depression Era. I personally discovered Eleanor Powell for the first time in this movie. She sure knows how to dance! Jimmy Stewart, who plays a clean cut sailor in this film, shows his talent, not just as an actor but as a singer and dancer as well. A little known Sid Silvers, who plays "Gunny Saks"in this movie is a short, stocky energetic dynamo who probably deserves more recognition, also is credited for the screenplay of the movie. Another actress I discovered for the first time when I saw this movie was Virginia Bruce and she is captivating in the musical number aboard the submarine with her Pekingese companion, "Cheeky". I had recognized the name but another actress who I had little knowledge of was Frances Langford and she is natural to dance with the young boot scooting Buddy Ebson. All of the other character actors in this film are a joy to see. The no-expense-spared musical number at the end of this movie is inspiring. Out of all the movies, I own, I watch this one over and over again, especially when I'm in a good mood.
