Once again, the new pic reiterates that Sigourney Weaver's Ripley and Michael Biehn's facially disfigured Hicks – if you remember, he was sprayed by acid blood in Aliens (1986) – are front and centre of the project. Depending on what day it was, Blomkamp indicated earlier this year that his Alien film would either somehow be set between Aliens and Alien³ (1992), or ignore Alien³ and Alien: Resurrection (1997) completely.
The specific details of the new film's story have yet to be revealed. The artwork above slightly puts us in mind of Mark Verheiden's Dark Horse comics series Aliens Book II, in which Hicks and Newt (Ripley wasn't with them at that point) arrived on a Company transport to be met by hostile military types. But that is almost certainly just coincidence.
Alien (1979) director Ridley Scott is producing, and the film is currently in pre-production with no release date set.
