Star Wars special effects to be added to the film with creator’s approval.

Post-production has been extended for Fanboys in order to add sound and special effects from the Star Wars films, according to a SCI FI Wire interview with the movie’s co-star Chris Marquette.

Star Wars creator George Lucas gave his consent for the additions after seeing an early cut of the comedy about a group of friends who drive across country to an advanced screening of Star Wars: Episode I: The Phantom Menace at Lucas’s Skywalker Ranch.

While the film’s principal photography was completed last year, Fanboy post-production process was extended to incorporate the effects and also to allow filmmaker Kevin Smith to shoot a cameo as well as to write and direct a scene in the movie. Smith, who directed Clerks and Jay and Silent Bob Strike Back, is an admitted Star Wars fan who often puts references to the scifi franchise in his own movies.

Fanboys stars Sam Huntington (Superman Returns), Dan Fogler, Jay Baruchel, and Veronica Mars heroine Kristen Bell as the friends who, along with Marquette, are making the pilgrimage to fulfill a dying friend’s last wish of seeing the first Star Wars prequel before its worldwide release.

The homage to Star Wars fans features special appearances by saga alums Carrie Fisher, Billy Dee Williams, and Ray Park (who played Darth Maul in Menace), as well as other notable cult icons William Shatner and Danny Trejo.

Fanboys theater release date is now August 17, 2007.
