In his cameo in this film, Tim Burton is holding something in his left hand that looks like a remote of some sort when we first see him in the background. Then the shot changes to Debbie and back to Tim, but this time he doesn't have it. Then the shot changes to Debbie again and then back to Tim, and he reaches to his far right and picks it up.
In the scene where Campbell Scott having a depression state, lying on his back on the floor, listen to the Jazz music in the background. It's the same music where Tom Cruise and Reene Zellweger having sex in Jerry Maguire. Apparently Cameron Crowe loves this song.
