Reagan had just entered the military and was assigned to making "This Is the Army" and then military training films. Scenarists Casey Robinson and Claude Binjoy came up with a story lined that worked in material from Berlin's 1917 soldier show "Yip, Yip, Yiphank." Set during World War I, Murphy plays a Broadway song and dance man who is drafted and put in charge of an army show. After the final performance the cast marches off to war, where Jerry Jones receives a leg wound. Then we jump to the start of World War II, Jerry is now a Broadway producer and son Johnny is his assistant.

History repeats itself, this time with Johnny enlisting and taking time to marry his sweetheart, Eileen Dibble (Joan Leslie), before marching off. The film offers Kate Smith singing "God Bless America" and the treat of Irving Berlin himself singing "Oh, How I Hate to Get Up in the Morning." This show also includes "This is the Army, Mr. Jones," which is probably the only other song contemporary audiences might still recognize, if you are old enough. Certainly "This Is the Army" is dated, but if you remember the time and place it does its duty well as a patriotic film exactly as it was supposed to do.
