* ActorAllusion: In the movie, a bluesy version of "Down To The River To Pray" from ''OBrotherWhereArtThou'' is heard after we're introduced to the "counselor", who was a member of ''O Brother'''s PowerTrio.
* PermanentPlaceholder: When Louis Sachar was writing the book, he used Stanley [[SdrawkcabName Yelnats]] as a filler name, planning to replace it later with a more normal name. He never did, and the weird name even ended up becoming a plot point.
* SelfAdaptation: Louis Sachar's draft of ''Holes'' almost wasn't used, but ultimately retained, and skewed far closer to the book than the other optioned draft with minimal edits.
* SoMyKidsCanWatch: Creator/SigourneyWeaver's daughter begged her to play the Warden.
* WhatCouldHaveBeen:
** [[Film/DonnieDarko Richard Kelly]] was offered the chance to do this movie. He was replaced when they saw his screenplay, which was set in a post-apocalyptic CrapsackWorld. It had ''nothing'' to do with the book. [[spoiler: Just to describe the tip of the iceberg, one of the major changes was that Stanley's crime was [[MercyKill Mercy Killing]] his plague-infected sister instead of stealing a pair of shoes.]]
** Kissin' Kate's signature KissOfDeath was originally going to be to wear lipstick made from rattlesnake venom. This was later changed to be the Warden's nail polish.
