The game manual featured throughout every version's cutscenes (except the DS version) is the cover from the Xbox 360 version. The DS version, however, is actually from the in-game cutscenes used from every other version. Interestingly, the DS version’s cutscenes resemble the in-game ones from the other versions.

All "in-game" cutscenes from the Xbox 360 and PlayStation 3 versions were imported to the PlayStation Portable, Wii, and PlayStation 2 versions of the game despite obvious inconsistencies with the level designs.

Unused victory fanfares for each stage can be found in the DS version's data. In the final game, the main menu theme replaces these.

The E3 2007 build of the Xbox 360 release revealed that the home console versions were originally meant to have cutscenes fully animated in 3D. A workprint containing these cutscenes shows a mix of finished and unfinished 3D renders and storyboards with placeholder voice acting, with the final game having cutscenes primarily animated in the same 2D digital animation as the show. The Nintendo DS version of the game is the only version that exclusively uses 3D cutscenes.

This build also reveals that the identity of the "sleazy video game producer" featured in Level 5: Mob Rules is Larry Probst, the former CEO of Electronic Arts from 1991-2007 whose name was censored from the script in the final game.
