Trivia: In the opening scene where Mia is introduced and waves to the crowd from atop a staircase, (wearing a big red dress) she accidentally flings a bracelet off her wrist, where a footman catches it.

Trivia: Kathleen Marshall, who plays the role of Charlotte, is the director Garry Marshall's daughter.

Trivia: When the Grinch takes the table cloth from the table, everything on the table was supposed to fall off. When Jim Carrey yanked out the cloth however, everything stayed in place. Jim immediately walked back to the table and improvised knocking everything off and then knocking the table over.
Suggested correction: There is no evidence this was a mistake.
There's an apparent scan of an original script on scriptslug.com that indicates the scene, as written, had him pulling the cloth without disturbing anything, then kicking the table over.
