Taylor Dooley - Production

Production

Parts of the film were shot on location in Texas, where Max resides and goes to school in the film. Much of the film was shot in a studio against green screen. Most of the ships, landscapes and other effects including some creatures and characters, were accomplished digitally. According to Lautner and Dooley, when filming the scene with the dream train, the front part of the train was an actual physical set piece. "The whole inside was there and when they have all the gadgets you can pull on, that was all there but everything else was a green screen," said Dooley. Eleven visual effects companies (Hybride, CafeFX, The Orphanage, Post Logic, Hydraulx, Industrial Light & Magic, R!ot Pictures, Tippett Studio, Amalgamated Pixels and Intelligent Creatures and Rodriguez's Texas-based Troublemaker Digital) worked on the film in order to accomplish over 1,000 visual effect shots.

Robert Rodriguez appears in the credits fourteen times, most notably as director, a producer, a screenwriter (along with Marcel Rodriguez), visual effects supervisor, director of photography, editor, a camera operator, and a composer and performer. The story is credited to Racer Max Rodriguez, with additional story elements by Rebecca Rodriguez, who also wrote the lyrics for the main song, "Sharkboy and Lavagirl". Other members of the Rodriguez family can be seen in the film or were involved in the production.

Miley Cyrus had auditioned for the film with Lautner, and said it came down to her and another girl who was also auditioning, however Miley began production on Hannah Montana.
