Revealing mistake: The film was rushed to theaters, leaving a few mistakes which Universal fixed. In the original cut, toward the end, Judi Dench's human hand is visible, complete with her wedding ring. This was fixed for the re-release.
Revealing mistake: Numerous times in the film the animals walk from shade into sunlight without their eyes reacting.
Revealing mistake: During the interview, you can see a monitor with the lyrics of "Something", even though he is supposedly improvising.
Suggested correction: This is a deleted scene. It is in the extras on the DVD but it is not part of the movie.
