Continuity mistake: In the "bar room brawl" scene where Roanoke and Guru Pitka are fighting the others in the bar, there's a scene in which there are two girls kicking Pitka's butt. In the first part of this, the girl on the left has a small braid on either side of her face but the rest is hanging down and quite frizzed. The girl on the right has hers braided neatly in two braids on either side of her head. The camera shifts to Roanoke and others and then back to Pitka, and the girls have now switched places.
Factual error: When Darren was kicked out of the first game, behind the referee that suspended Darren, there was another one with orange stripes. The one referee that was grabbing Darren to bring him off the ice also had orange stripes. All three had stripes. In a real game, only two of the referees have stripes.
