Continuity mistake: In the second to last scene of the film, Michael Williams jumps onto a very long train pulled by southern Pacific Railway locomotives. In the last scene a pan shows a train rolling into the distance some hours later (the sun has come up) and the train is now very short and pulled by a Montana Rail-link locomotive. Either the train has seriously changed since we last saw our hero, or the director just took a pan of any old train in a setting he liked.
Continuity mistake: When Michael and Suzanne are in the bar after having escaped from Lyle, there's a shot of Michael taking a drink of a beer, and then putting it down on the table. In the next shot, which is of Suzanne, we can just see Michael's arm, and he's putting the beer down again, without ever picking it up.
