Well looks like that pretty much rounds out a cast, then! Of the bunch, Spaeny is the only one I have any actual familiarity with, I believe, thanks to
Devs and (ugh)
Pacific Rim: Uprising. Fearn is mentioned as having been in
The Batman, though I'd be lying if I said I remember him in the movie based on that photo of him.
Seems like the article has a little bit of a synopsis for the film, too:
QuotePlot details are being kept in a cryochamber, but as opposed to the other movies which focused on adults in corporate, militaristic and scientific roles, this now-ninth installment of the franchise will focus on a group of young people. On a distant colony, the group finds themselves in a fight for their lives with the titular alien, a creature known as a Xenomorph, whose race propagates by implanting eggs into people's stomachs via face-huggers, with the juveniles eventually violently bursting out of the host's chest.
So we have a setting, a colony world.
