Logan Marshall-Green (Devil) is the latest actor to join Ridley Scott's Prometheus. According to Deadline Hollywood, Logan will play the role of "Holloway, a crewman on the space ship and the love interest for the character played by Noomi Rapace". He will be joining the growing cast list, which includes Noomi Rapace, Michael Fassbender, Charlize Theron, Idris Elba, Sean Harris and Kate Dickie. Prometheus starts filming this month and will be released in theaters on June 8th, 2012.
Ridley Scott has yet to got on record since the initial Prometheus announcement to clarify confusion regarding how this ties into the Alien universe. Based on actor comments and a number of other reports, Prometheus appears to be directly tied to Alien, but we'll have to wait a little bit longer for more details.
