Continuity mistake: After escaping Bean Annex on the motorcycle by going off the ramp, Kylie turns back, sees the wolf and does a double take, and tells Mr. Fox "don't turn around". But when everyone looks at the wolf in the next shot when the motorcycle has stopped, they're looking off to the side of the road, not behind them. (01:11:20)
Continuity mistake: When the gang are making their escape from the farmers, they ride a motorcycle up a ramp and crash through a paper banner. We see this twice in consecutive shots, first from the point-of-view of the gang, then again from the side.
