Continuity mistake: Near the end of the film when Spider Mike is rescued from a town. The Rubber Duck's truck is damaged. It loses the bullbars on the front, and the windbreaker on the roof is flattened against the roof of the cab. Yet after leaving the town, in a series of shots showing the Rubber Duck's truck. The damage disappears or varies. The windbreaker appears fixed and so do the bars, but in the next shot just the windbreaker is fixed and the bars aren't. It continues like this through a montage and then in the next scene when it cuts back to a close up of the truck both are damaged again. (01:47:40)
Continuity mistake: Henry Moon is too 'street smart' to have left gold dust on the mining tools for someone to find.
Revealing mistake: While Billy and Eli are on the river, with Eli in the front and Billy in the background, pay attention to Eli's paddle. When it passes in front of Billy, you can see right through it to see Billy through the paddle. (00:56:25)
