Continuity mistake: The rabbits have a close encounter with some rats in a shed on the cemetery. A spade falls over. In the next shot the spade lays in a wheelbarrow.
Suggested correction: No, the spade isn't visible in the wheelbarrow; you can see it next to Fiver.
Continuity mistake: When Bigwig sees Hyzenthlay and Blackavar from a distance, Blackavar's ears are intact at first, but then in the next shot they are broken as they should be. (01:01:16)
