yeah the one who is stepdad to an incest baby, and is all around a chill guy. oh, he' also the stone skin curer?

in the moon movie he's an american who's somehow british, and a moon conspiracy theorist. he teams up with Halle Berry and the guy from the Insidious movies

so the trailer to Greenland 2: Greener Lands first talks about "Oh no we can't live in the Vault from Fallout all our lives, shit's boring" and then they leave the vault to go on quests in the apocalypse zone. so that looks like the second half of the moon movie where people are going on some quest driving cars around barren landscapes as meteorites rain.
