Plane Daffy (1944)
1 audio problem - chronological order
Directed by: Frank Tashlin
Starring: Mel Blanc, Sara Berner, Robert C. Bruce
Continuity mistake: When Daffy flies into the squadron headquarters, you can see that the strap on the left-hand side of his helmet is resting on his arm, but in the next shot the strap is directly behind him.
Trivia: Even though Daffy Duck is the main character, he doesn't actually appear until the cartoon is over halfway finished.
