Corrected entry: After Depp talks about the Manson family, look to the right of the hitchhiker. You will see (what I'm assuming to be) a white crew truck as they drive past.
Corrected entry: When the photographer comes to meet Raoul (who is crouched behind the mini-bar) there is a tray with an ice bucket and glasses. As he is explaining the various bikes present at the sign in for the race the ice bucket disappears.
Corrected entry: When Duke is having the LSD licked off his sleeve in the bathroom of the Matrix, a man walks in and has 'his life ruined forever'. The mistake is that this man zips up his pants before using the bathroom, he zips then up while entering. It is obvious that this is the entrance because of the backwards 'MEN' writing on the doors' window.
Corrected entry: In the scene where Duke is speaking to Dr. Gonzo from the phone booth after being chased by the cop; the scene is being played backwards, as there is smoke disappearing into a car behind the phone booth.
Corrected entry: In the beginning of the film when Duke is going through all the stuff they brought with them he points to a bottle of liqour and calls it tequilla. Yet it is clearly a bottle of Wild Turkey.
Corrected entry: In the scene where Duke is being persued by Highway patrolman Gary Busey, he is looking in the rear view mirror while his left hand is turning on the left turn signal (missing it the first time then succesfully on the second attempt). The next shot is him saying something about the officer not knowing what to make of the turn signal indicating he's about to pull over and the camera shot clearly shows Duke turning on the left turn signal which we have already seen him do.
Corrected entry: The red Chevy convertible is supposed to be a brand new car, but during the police chase scene, the odometer reads over 70000 miles.
