Continuity mistake: Bugs Bunny shows his displeasure with Marvin Martian by keying the Martian Maggot. Later when Bugs Bunny pulls the "Lost Tourist" joke (and wins $5.00 from Daffy Duck) the scratch on the Martian Maggot is repaired.
Continuity mistake: When DJ and Daffy leave, the car that comes up from the revolving floor is a TVR Tuscan,but when Kate and Bugs,leave for Las Vegas in it, it turns into a Lotus Elise.If you live in Europe, and like cars, this is easy to spot,because the Lotus is and open top car with a flat rear-end, while the TVR is a closed roof car and has a rounder rear-end.
Continuity mistake: In the scene with DJ and Daffy Duck in DJ's house, Daffy throws an apple at DJ's face and hits him on the cheek. In the next shot, DJ's rubbing his forehead, as though he got hit there.
