Continuity mistake: Before the start of the match, the teams line up and acknowledges the spectators. In the number 7 shirt for the Allies is John Wark, yet at the start of the second half, the same player is wearing a red track suit and sitting on the reserves bench. At no point was he injured or replaced.
Continuity mistake: At half time the POW team climb into a hole that leads to the tunnel and argue about going back. The tunnel has just had gallons of water flow through it from the bath, but the team come back all clean and their feet aren't even muddy.
