Continuity mistake: Near the end of the movie, Lucinda is severely injured in her leg, and has to hobble to walk. In the last scene (a short time later) as she approaches her home, she is walking with no problem, and has her arm in a sling.
Other mistake: When Jack Warner puts on the Corporal's uniform how is that possible when he's handcuffed to George Cole? (00:16:00)
