Starring James Cagney and an array of others, the film tells the real life story of writer, singer, and dancer George M. Cohan. The story begins with an older Cohan recounting his life story. He began his career with his family in Vaudeville. Slowly he made a name for himself in Broadway and married his love. He and his partner kept making musicals and then the Cohans reunited for one last show. Eventually everyone in the family settled down before they died. The only one left was George who was living with his wife. In his final performance, Cohan gets the country to rally around the flag again as he has done his whole life. This movie has many commendable moments but there is an apparent conflict between biography and musical. Cagney for his part gives a stellar performance as the energetic and ambitious Cohan. The film also doubled as a nice piece of propaganda during World War II.
