First, let me say that Thomas Newman did an awesome job with the soundtrack.
But there seems to have been a possible outtake. It's the music during the train scene, which should be heard under the track "An Unpleasant Incident Involving a Train". However, that particular cue isn't heard in the movie. Instead, the correct music can be heard on the track "Hurricane Herman", yet that version is more of a spliced reprise of the actual theme, as well as certain variations. It's possible that the producers found "An Unpleasant Incident..." not well suited for the scene and asked for something different, but it showed up on the CD anyway. If anyone has any information on this or where to find the actual cue, please respond.
