* ActorInspiredElement: DustinHoffman completely ad-libbed Mr. Magorium's lisp. His contract also stipulated that he was allowed to do his own hair.
* CreatorBacklash: Zack Helm [[http://www.tmz.com/2013/09/24/breaking-bad-mr-magorium-emporium-walter-white-movie/ has described it as "a Technicolor train-wreck"]] and stated, jokingly or not, in response to a ''Series/BreakingBad'' 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.
* OneBookAuthor: This is to date the only film directed by Zack Helm (he is better-known as the writer of ''Film/StrangerThanFiction''). The project also served as a CreatorKiller, as he's only done script doctoring work since.
