Ian McShane has joined the growing cast of Hercules for MGM Studios and director Brett Ratner.

Dwayne Johnson stars as the title character, based on the Radical Publishing graphic novels that take a different approach to the Greek god. Instead of being the son of Zeus, Hercules is a fierce mortal who is feared by many. When he leads his group of mercenaries on their latest mission, the job turns out to be much more complicated that previously imagined.

Ian McShane is playing Amphiarus, a priest, prophet, and warrior who serves as Hercules' adviser. Aksel Hennie and Rufus Sewell also star as Tydeus and Autolycus, other members of Hercules' group.

Brett Ratner is directing from a screenplay originally written by Ryan Condal (Paradise Lost), which is being polished by Evan Spiliotopoulos (Wanted 2). No production schedule was released at this time.

Ian McShane most recently starred in Jack the Giant Slayer and Snow White and the Huntsman, along with a memorable turn as a murderous Santa Claus on the FX anthology series American Horror Story.
