Robert Pattinson to star in The Rover, Kristen Stewart sorry for being one

Twilight star Robert Pattinson is continuing his march away from the mainstream after signing on to appear in futuristic western The Rover for Animal Kingdom director David Michod . Michod made a huge splash with his 2010 debut , the tale of a family of Melbourne gangsters who take in their recently orphaned teenage cousin. The Rover, which is set in the Australian desert of the near future, will also feature Animal Kingdom's Guy Pearce, as a man who hunts down a gang of thieves that stole his car. Pattinson, who won praise for his turn in David Cronenberg's Cosmopolis , will play the brother of one of the thieves, who is left behind when a police encounter goes wrong. In a separate development, Twilight star Kristen Stewart has apologised for cheating on partner Pattinson with the married director of Snow White and the Huntsman , Rupert Sanders. Stewart, 22, and Sanders, 41, were photographed together by a paparazzo whose shots were featured in Us Weekly. Sanders, who directed Stewart and his wife Liberty Ross in Snow White and the Huntsman, has also apologised. Stewart said: "I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected. This momentary indiscretion has jeopardised the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry." Sanders, who has two children with Ross, 33, said: "I am utterly distraught about the pain I have caused my family. My beautiful wife and heavenly children are all I have in this world. I love them with all my heart. I am praying that we can get through this together." Pattinson and Stewart are one of the highest profile couples in Hollywood. The four Twilight films so far have taken more than $2.5bn at the box office.
