Audio problem: During David and Alan's argument in the rainstorm, neither actor's lip movements match the dialogue. (01:14:00)
Continuity mistake: After the British soldier is shot, David Balfour finds Alan Breck hiding in the brush. Breck has a visible beard stubble that disappears a few shots later.
