Factual error: Willie opens the secret room in the Collins family mausoleum, and a flock of bats flies out. It's a hidden chamber that's been sealed (without even small openings - it's imprisoning a vampire) for 200 years. There'd be no way for the bats to get in. (00:15:00)

Continuity mistake: When Julia comes to the Old House to confront Barnabas, Willie lights a tier of four candles, but one goes out again, leaving only three burning. In full shot, candle 4 remains unlit. In a close-up from the same angle, candle 4 is burning and 3 is unlit. (00:41:50)
