From their humble beginnings as Dragonslayer – whether or not they were actually called that – this four-hour film will be told through a sword-and-sandals story, with animatronic puppets supplied by the Henson company. Think of it as Labyrinth-meets-Spinal Tap. In their bid for metal supremacy, the band fight orcs, liberals and lily-livered posers in a quest that never quite seems to end. Directed by Michael Bay, the film will star Aquaman’s Jason Momoa as Tom Araya, Die Hard’s Alexander Godunov as Jeff Hanneman, Tom Hardy as Dave Lombardo and Kyle Gass as Kerry King. Look out for a fairly amusing walk-on part by Adam Sandler as the devil.
