process began in 2002. Gilroy became involved after a meeting with Thompson, and enjoyed working on the script as he greatly admired the Bionicle mythos. Two draft scripts were originally created to see who would write the better script: one by Swinnerton, and one from Gilroy. Due to time constraints, the Gilroy script was accepted with some of Swinnerton's ideas included. Gilroy's most difficult task was creating the dialogue for the Toa: he needed to take into account Thompson's own interpretations, and what the majority of fans thought they should sound like. In the end, he attempted to stay true to original portrayals while giving the voice actors something unique to work with. He also needed to balance their portrayals and screentime, as each of the six needed a chance to shine. The script went through eight different drafts before the final version, although this was far less than Gilroy was used to seeing on other projects. During planning stages, a lot of time was devoted to how characters interacted with each other: cited examples were Lewa's style of speaking, and Kopaka's stoic behaviour. These traits were accentuated for the film to give the characters more distinction and depth. He also needed to avoid putting in out-of-context pop culture references, which would not fit into the setting of Bionicle. As part of the world and character development, expressions and exclamations unique to the world were created: a cited example is Jaller saying "You could have been Lava-Bones" when Takua narrowly escapes being killed by a flood of lava. Design The characters of Bionicle had been portrayed in various ways across multiple media, including the official comics, Flash animations used for online videos, and CGI commercials for the sets. The team decided to use the models from the CGI commercials as their working base for the film models. Before commencing with designing the characters, the team went to Lego's Denmark headquarters and received lessons in the Bionicle design process. The team were originally not going to alter the characters that much, but they needed them to be emotive, which necessitated a redesign. The first step in creating the character models was redrawing the skeleton, then adding muscle pods that would interweave with the skeleton: the muscle gave the characters a more textured appearance, and were added to the shoulders, calves, abdomen and chest cavity. Each character was given a "heart light",
