But it doesn't stop there, it again cuts away for a few seconds and when it comes back to a a shot of the clock it now reads 11:40.

Continuity mistake: In the outdoor restaurant scene (where Tim Robbins has just spoken to Burt Reynolds), the waiter brings Tim Robbins a bottle of water and a wine goblet, but when he pours the entire bottle of water into the goblet, it's obvious that it was not a full bottle of water to begin with. It doesn't fill the glass of half way. A waiter would not serve an opened bottle of water to a diner.

Continuity mistake: When Levoi and Crowhorse visit Grandpa for the first time note the white and black beaded belt on the table behind Grandpa.

After that cut the belt now hangs in its original position. (00:37:30 - 00:38:30)

Continuity mistake: When Eddie Murphy is on a duck hunting trip with a bunch of gun lobbyists, the lobbyists are firing their M16 rifles at a bunch of ducks that are flying by. You can clearly see them squeezing the trigger and not a single shell case is coming from the chamber of the gun. Also, when you fire a gun there is usually smoke from the muzzle but in the movie there is no smoke, yet you hear the sound of several guns firing. (00:55:00)
Continuity mistake: When Duncan tries to explain his version of the raid of the Camerons' lodge to Cora part of his uniform is a read seat-belt-like piece of cloth. This wasn't there in the scene preceding imediately. (00:47:30)

Continuity mistake: Near the end, when the hitman walks out of the diner, the camera focuses on the car in the parking lot, cuts back to the hitman, then cuts back to the car. The problem is the shadows in the first shot of the car are about half a meter long, but a few seconds later they are two meters long. Obviously both takes of the car were taken hours apart.
