Yankee Doodle Dandy (1942)

Visible crew/equipment: In the final musical number "Strictly off the Record", you can clearly see the shadow of the microphone boom during part of the number.

Continuity mistake: In the dressing room scene just before Mr. Albee's visit, as Jerry Cohan is talking he wraps a scarf around his neck. He leaves one end outside of the dressing gown, but in the next shot, both ends are tucked in.

Factual error: Although quite typical for biopics of this era, certain aspects of Cohan's life are glossed over. The movie shows him in a lifelong marriage to his first love. However, he was in fact married in 1899 to Ethel Levy, and after their divorce in 1907 he married Agnes Mary Nolan, who remained his wife until Cohan's death in 1942.
