Continuity mistake: When the soccer match ends, Prof. Brown comes crawling, the amount of weeds and their position on his head differ between the first and second angle in less than half a second.
Continuity mistake: When the Germans are in Ms. Price's house, the German officer quickly hands a paper to a soldier who comes running. Watch how the soldier, in his hurry, misses by far and grabs the officer's arm at elbow level. In the close-up he corrects the position and is now grabbing the paper.
Revealing mistake: When the ghost army starts to move, the wires holding the drum sticks are visible.

Other mistake: The interiors of Miss Price's house is definitely not from a British country house. The ground floor looks more like an American 70's house.
Continuity mistake: When Miss Price and the children are first en-route to London on the bed, Paul is holding his cap in some shots (from the side and front) and not at all in the shots from behind him and his sister.
