Other mistake: In the brief scene in which Nicholas Andre and J.P. Shay are talking about the killing of the owl at the preservation society ball, if you look very closely out the very bottom of the window, at the very end of the short scene (right after Andre says, "Their guys aren't just anybody, they're good"), you can catch a brief glimpse of part of the box containing the victim who is trying to escape (this box was completely excluded from the film).
Other mistake: You have to know Colorado to get this one, but the two guys are on a trip to Aspen to return the suitcase to the woman. But when they finally arrive, they are not actually in Aspen like you are supposed to assume they are. The whole Aspen scenario actually takes place in Breckenridge ski resort. (00:54:10)
Other mistake: At the start of the film when Lloyd pulls up next to the Austrian woman, despite being tinted we can see through the limo's window. We don't see Lloyd climbing from the front to the back of the car, nor do we see the car rocking slightly which it would have done if someone was moving around inside. It's also impossible for him to get from the front to the back of the car in the time given.
Other mistake: In the scene where Lloyd hears footsteps approaching his bathroom stall, he locks the door so that Sea Bass can't enter without forcing it open, as seen in the following shots. But if you look closely at the space between the partitions as Lloyd turns the locking handle, you can see how the bolt moves only halfway between the door and frame thus never actually locking. (00:48:05)
Other mistake: On the subtitles for the UK "Uncut" DVD (I'm not sure if this applies to other "Unrated/Uncut" DVDs), the subtitles mix up the character names during one shot. As Lloyd goes in the wrong direction, the film cuts to a shot from behind the pair. Harry says that he "expected the Rocky mountains to be a little rockier than this." The subtitles incorrectly state that this line was said by Lloyd. Lloyd's response that "John Denver is full of shit" is also incorrectly attributed to the wrong character; the subtitles say Harry said that.
