Continuity mistake: Nicky is crouched down behind the wall, listening to the chief robber telling the villagers what his gang is going to do. One of the robbers throws a chain over the wall, nearly hitting her. Nicky ducks her head down to avoid the chain hitting her, but when the angle changes Nicky's head is upright and she ducks a second time, also she has moved back along the wall a little way.
Revealing mistake: Whenever Isis has to do jumps you can tell it's not her but a stunt double.
