* 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. [[AlteredStates William Hurt]] as Professor Allen Hobby and [[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 JustShootMe is the killer who framed Gigolo Joe.
* HeyItsThatVoice: [[WesternAnimation/TheTransformers Omega Supreme]] is a teddy bear.
** There's also [[Film/ShutterIsland Dr. Cawley]] as the Future Mecha [[note]][[ActingForTwo and a Technician]] & TheNarrator[[/note]], [[ReturnOfTheJedi Bib Fortuna]] as a Gardener, ChrisRock as the comedian robot and Creator/RobinWilliams as Dr. Know. MerylStreep also appears as the Blue Mecha.
** Despite being on-camera, Sabrina Grdevich (better known to some as [[TheOtherDarrin the original]] [[Manga/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 (''SchindlersList'' made Kubrick give up on [[http://en.wikipedia.org/wiki/Wartime_Lies a similar adaptation]], and ''JurassicPark'' convinced him that CGI could bring the project to life). Then he wanted to start the project after ''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.
