The 1942 film Yankee Doodle Dandy is a biography about "The Man Who Owned Broadway", George G. Cohan.

Still, he approved of Cagney's portrayal and managed to see the film thanks to Warner Brothers moving up the scheduled gala premiere from July 4 (Chosen as Cohan actually was born on that day) to May 29. And because of this, Cohan lived for several more months after the film's release. But his name was etched deeper in history because of the film. Stay tuned!
