Trivia: Mr. Magorium's Wonder Emporium
- Actor-Inspired Element: Dustin Hoffman completely ad-libbed Mr. Magorium's lisp. His contract also stipulated that he was allowed to do his own hair.
- Creator Backlash: Zack Helm has described it as "a Technicolor train-wreck" and stated, jokingly or not, in response to a Breaking Bad joke that the only DVDs Walt has to watch while in hiding are two copies of this movie, that "Walt has exactly two more copies then are allowed in my house." It's ambiguous as to whether he was serious or not.
- One-Book Author: This is to date the only film directed by Zack Helm (he is better-known as the writer of Stranger Than Fiction). The project also served as a Creator Killer, as he's only done script doctoring work since.
