Revealing mistake: In at least one scene, you can see the ruts that the filmmakers made in the greens to make Happy's putts go where they wanted them to.
Revealing mistake: In many scenes, particularly the dance scene in the bar, Michael's wings disappear and/or reappear. If you look closely throughout the movie, his wings are often completely gone.
Revealing mistake: Hamlet is killed and in the next scene is being carried with his arms stiff to his sides. The men carrying him go over a bump, jolting Hamlet, and he blinks.
Revealing mistake: In the scene where Romeo and Roy snap all the clubs other than the 7-iron, Roy drops his golf ball onto the grass. However, when he hits the ball, a white tee can be seen travelling up towards the top left of the screen. The tee can easily be seen but is much clearer in slow motion.
Revealing mistake: When the car at the end flips over, you can see a circular object underneath the vehicle, about the size of a tyre (very obvious in slow motion). This is the device that "lifts" the vehicle for it to flip on one side, timed with the appropriate explosion.
Revealing mistake: When Jamie and Sandra are arguing and rolling about on the floor in their lounge, the microphone powerpack on Jamie's back is visible through his t-shirt. (00:32:05)
Revealing mistake: When Martha is in her office and the phone rings, when the camera shows the phone, no line is lighting up, yet when she picks up the phone everything is normal and the phone conversation starts. Having owned one of these phones, first of all since they are multi-line phones when a light is flashing green that means an incoming call and a solid red means a line is being used but none of this stuff shows up in the scene. Second of all, the secretary earlier on in the movie says she has a call on line two, therefore proving she has more than one line on the phone.
Revealing mistake: When the Teacher and Juliet make love there's a sheet wrapped around the teacher's hips, and after the climax his sweaty hair dries between shots. (01:15:40)
Revealing mistake: On their wedding night Rose and Greg watch 'Lawrence of Arabia' on video, lying in their separate beds. When the movie is over Rose comes and switches the TV off, but before she does that you see a reflection of her in the TV where she is standing there and waiting for her 'turn'. (01:02:35)
Revealing mistake: When they attach a GPS device to the gang's car and they watch their situation on the computer screen, you can see on the left top part of the screen some playback, stop, rewind, . buttons, showing that it's a pre-made video that they play manually.
Revealing mistake: When Buddy throws Reggie at the piano, you can see it's his stunt double instead of Buddy.
Revealing mistake: When Sassy comes out of the burning house carrying the kitten in her mouth you can tell that the kitten is fake.
