Arnold Schwarzenegger is following in the footsteps of Brad Pitt by taking on an army of zombies in his latest movie. The Terminator star, who returned to acting after stepping down as California Governor in 2011, has signed up to star in new horror blockbuster Maggie, in which he will play a father whose young daughter is infected by a zombie virus. Chloe Grace Moretz had initially agreed to play Schwarzenegger's onscreen daughter, but had to drop out due to scheduling conflicts, according to Variety.com. Production on the film is due to begin in the autumn (13) before Schwarzenegger is back in action for a new Terminator movie. Zombies look set to dominate movie theatres across the world this month (Jun13) following the release of Pitt's big budget blockbuster World War Z which documents a global plague of the undead.
