Weta Workshop will design the costumes for "Happy Feet" director George Miller's adaptation of the "Justice League" comic series reports The Dominion Post.

No budget has been announced for the long-awaited movie, which would bring together a range of superheroes including Superman, Batman, The Flash, Aquaman, Wonder Woman and Green Lantern.

Barrie Osborne ("The Lord of the Rings") will produce and confirmed that it was possible Weta Digital could also be involved in the film to do the CG visual effects, but that would depend on the studio's commitments to other projects.

Production on the superhero team-up feature gets underway in Sydney, Australia shortly.
