Ridley Scott has plumbed for a relative unknown actor to play Noomi Rapace’s space-bound love interest in Prometheus. Deadline confirm that Logan Marshall-Green has just signed on to the role in Scott’s belated, distant cousin to Alien. Marshall-Green will play Holloway, a space craft crew member, and a love interest for Rapace’s Elizabeth. The 34-year-old actor was last seen on the big screen in lift thriller Devil and Brooklyn’s Finest, while he’s also done TV work with The O.C. He joins Michael Fassbender, Charlize Theron, Idris Elba, Sean Harris and Katie Dickie. Filming on Prometheus will commence in the UK this month.
