A combat picture was virtually a license to print money in 1942, and RKO Radio's The Navy Comes Through was no exception (net profit: $542,000). Most of the film takes place on the ramshackle old merchant-marine freighter, skippered by Captain McCall (Ray Collins). The captain and his stalwart crew-the most stalwart of which are Mallory (Pat O'Brien), Sands (George Murphy), Babe (Jackie Cooper), Tarriba (Desi Arnaz) and Berringer (Max Baer Sr.)-keep busy by blowing Nazi bombers and U-boats to smithereens. The crewmen cap their accomplishments by capturing a Nazi supply ship and using it against its own navy. The easily forgettable romantic subplot concerns Sands' on-and-off relationship with Myra (Jane Wyatt). The Navy Comes Through was inspired by Borden Chase's serialized Saturday Evening Post story "Pay to Learn".
