Continuity mistake: When the hole is being punched in the ceiling and gets larger and larger, one shot reverts to when it was barely started.
Factual error: As Augusten Burroughs is taken to his mother's physician's home to stay, he notices Dr. Finch's wife, Agnes, intently watching the vampire soap opera "Dark Shadows." However, the year has been previously indicated as 1978 and Dark Shadows ran before that, from 1966 until 1971, so it couldn't have been on television.
Suggested correction: Dark Shadows would have been running in reruns at that time.
