Audio problem: During the scene where Jim and Owen are trying to bribe the Vicar with chocolates, just after they take them back, you can hear a mysterious voice say "chocolates". The only person who this sounds like is Jim, but in the next shot, his lips aren't moving.
Factual error: In the scene where they are gathered to watch the episode of Songs of Praise in the shot of Alice's reading. Her quote 'from the sixth chapter of the Song of Solomon, beginning at the second verse' "ye are the fault [salt] of the earth and fainted [sainted]." doesn't exist.
