CHUD.com was tipped off that Guy Pearce has joined the cast of Ridley Scott’s Prometheus. If that is indeed true, he joins Noomi Rapace, Michael Fassbender, Logan Marshall-Green, Charlize Theron, Idris Elba, Sean Harris and Kate Dickie. No word yet as to who Pearce plays. The actor previously starred in L.A. Confidential and Christopher Nolan’s Memento. Scott is presently in England shooting Prometheus – an Alien prequel of sorts – for Fox. It opens June 8, 2012.
