EA had originally planned to add Gollum as a playable character. This ultimately did not come to fruition for the PC version and almost every console version of the game, but he was added to the GBA version of the game.

One leftover detail indicating his planned playability is an in-game results screen template with Gollum's face faded in the background, which is located in the Cheat Codes menu of the game. Every playable character in the game has a screen like this, with Gollum being the only non-playable character to have one.
