Revealing mistake: Just before Jake is checked into the Surf Hotel, there is a long scrolling shot following the car and shows where Jake's room will be. In particular, there is the Kennedy Fried Chicken sign with one window above 'Chick' and one above the 'K'. After checking into the hotel and the guards leave, we see Jake outside of his window. This shot involves a recreation of the original location because the two windows are now above the 'nnedy' and 'en'. Furthermore, the lights surrounding the sign have changed (some are burnt out or missing, and they don't flash at the same time interval).
Revealing mistake: During the Unsolved Mysteries scene, a man is about to play solitaire. Look at the screen, though. It's already dragging cards around.
Revealing mistake: When Gus is reading "Sporting News" on the bus right before they meet Tanaka, the headline talks about the Buzz moving to third place. The article, however, is about a trade in the major leagues. (00:32:05)
