Continuity mistake: When Danny is speaking with Dolores about the food she is preparing, in the first shot his lips are moving as he's speaking to her but in the second shot a moment later, they are not. (01:50:55)
Visible crew/equipment: When Pat and Tiffany arrive at the hotel for the dance competition, in the first shot inside the building, the camera is shown moving forward towards them. To the left of shot, the reflection of the camera and cameraman can be seen in the glass window. (01:38:48)
Continuity mistake: Deniro starts taking off his jacket at the dance competition and it's halfway off his left shoulder. In the next shot his jacket is back on.
Chosen answer: Their score was pretty bad, but just good enough to win the bet. Getting the money was the important part - they didn't really expect to win the competition.
