* AuthorExistenceFailure: Fortunately, Spielberg was Kubrick's backup director.
* DoingItForTheArt: Jude Law worked with a choreographer for months to nail down Gigolo Joe's dancing and general mannerisms.
* HeyItsThatGuy: Besides Osment and Law, there's Brendan Gleeson, aka [[Film/HarryPotter Mad Eye Moody]], as Lord Johnson Johnson. [[Film/AlteredStates William Hurt]] as Professor Allen Hobby and [[Series/LizzieMcGuire Jake Thomas]] as Martin Swinton. ''Series/TheBigBangTheory'''s Kevin Sussman makes a minor appearance as a Supernerd, and so does [[Film/TheAvengers Agent Phil Coulson]]. And both of them work for [[IncredibleHulk General Ross!]]
** And Elliot from ''Series/JustShootMe'' is the killer who framed Gigolo Joe.
** Martin's father is [[Film/AmericanBeauty one of the Jims]]!
** [[Series/{{Lost}} Miles]] does quality assurance on sex bots!
** [[Series/TheBigBangTheory Stuart]] is a "supernerd"

Creator/MerylStreep also appears as the Blue Mecha.
** Despite being on-camera, Sabrina Grdevich (better known to some as [[TheOtherDarrin the original]] [[Anime/SailorMoon Sailor Pluto]]) cameos as Sheila.
* SavedFromDevelopmentHell: Kubrick read the story and hired the author to write a treatment in the early 1970s, invited Spielberg to work with him in 1985, and only decided to take the project off after Spielberg's '93 productions (''Film/SchindlersList'' made Kubrick give up on [[http://en.wikipedia.org/wiki/Wartime_Lies a similar adaptation]], and ''Film/JurassicPark'' convinced him that CGI could bring the project to life). Then he wanted to start the project after ''Film/EyesWideShut'', [[AuthorExistenceFailure but his eventual death]] in 1999 lead Spielberg to fully take over.
* WhatCouldHaveBeen:
** Stanley Kubrick was the original director, but the film languished in DevelopmentHell until Kubrick died in 1999.
** Gigolo Joe was originally conceived by Kubrick as a GI Mecha, but screenwriter Thomas Watson suggested changing him to a male prostitute.
** Chris Cunningham was originally the special effects supervisor when the project was being developed in the early '90s. None of his work ended up in the final film.
