[[AlteredStates William Hurt]] as Professor Allen Hobby and [[LizzieMcGuire Jake Thomas]] as Martin Swinton.

* 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.
