Continuity mistake: In the scene where Griffin is marketing the yellow sports car to a customer in the dealership, he laughs out loud while fooling around in one shot, and as the camera changes, his face is straight, and when it changes to the previous camera, he is laughing and fooling around again.
Continuity mistake: Neil McCormac - the main character - has a bust up with his American girlfriend. From the first angle he has only got a T-shirt on, then the camera changes angle and he suddenly has a sweater on. Then the camera angle goes back again and he's lost the sweater again. (01:15:00)
Revealing mistake: During the opening musical number, right before Gary joins the large group of people for the dance, he accidentally kicks Walter out of frame. Watch closely though. His foot comes nowhere near Walter when he supposedly "kicks" him.
Continuity mistake: When Tick Tock freezes Rebecca and Cecil, they are in one position, and when they go to the close up of them frozen, they are in a different position. When it zooms back out again they are in the first position. Also, when they are frozen moving on the conveyor belt, they are back in the position they were in on the close up shot. (00:47:50 - 00:48:10)
Other mistake: In the beginning the guy cuts a triangle in a banner, but the inside piece is floating.

Continuity mistake: When George Clooney is deciding whether or not his family's land holding will be sold to a corporation, he is sitting with two of his cousins. From a front view, his cousin, Hugh, opens a book. Then the shot switches to a side view, and it shows Hugh still opening the book.
Continuity mistake: When Boyle arrives in his police car at the house where McCormick is murdered, he turns off his engine and his windscreen wipers are pointing towards the sky. In the next shot you see the windscreen wipers in their normal position again.
Other mistake: Jacob takes Cal shopping. In the shot during which Jacob says to Cal "the skin under your eyes is starting to look like Hugh Hefner's ball sack," the film is flipped and the viewer is watching a reverse (or mirror) image. This is revealed principally by the fact that the emblem on Cal's Polo shirt is on the right side of his chest as opposed to his left.
Continuity mistake: When Tasha walks into Tyrone's bedroom, Tyrone is only wearing his boxers, but in the next shot he has grey joggers on.
