The Great Piggy Bank Robbery (1946)

Continuity mistake: When Daffy Duck appears from the mail box, the red flag is pointing up. In the next shot, it is pointing to the left.

Continuity mistake: When Daffy is peering through his hand to look at the Dick Tracy comic, he is lying on grass in the garden. But when we see him in the next shot, he is now in the field.

Continuity mistake: When Daffy realises he's Duck Twacy, he breaks the two telephones on his desk. But when we see the telephones in the next shot, they are now completely intact.

Trivia: When we see Daffy's silhouette in the door of Duck Twacy's office at the start of the dream sequence, the silhouette of Daffy briefly changes twice into Dick Tracy's silhouette.
