Revealing mistake: When Dog and his gang are locked in the cage, the guy holding the Bren gun opens fire. He does this without warning, but look at Dog's face. He flinches a split second before the gun is fired.
Continuity mistake: After Winston opens the cage and lets Dog and his gang into the house, Dog grabs him and headbutts him hard in the face, but Winston has no blood, bruises or swelling on his face at any time afterwards.
Suggested correction: Later that day, when he is being interrogated by Rory, there is definitely a mark on his forehead.
Continuity mistake: When Gloria picks up the Bren gun, we see Winston and Charles sitting up looking at each other in surprise, but seconds earlier, both had been tied up on the floor.
Plot hole: When the gang opens the gate and enter the house, Dog violently headbutts Charles in the face, but immediately afterwards and throughout the rest of the film, there are no cuts, bruises or swellings on Charles' face.
