During SiriusXM’s Town Hall Radio hosted by Entertainment Weekly’s Jess Cagle, Neill Blomkamp and Sigourney Weaver couldn’t get into too many details about that Alien reboot, but Weaver did reveal one (vague) thing: “Let’s just put it this way,” Weaver teased, “We’ve found the host and it’s been embedded…it’s gestated.”

Also on the panel were Chappie castmembers Jackman, Dev Patel, and Sharlto Copley, who talked about the just-released sci-fi film, from the inspiration behind it to Copley feeling the need to perform many of his own stunts. Weaver has a lot of sci-fi expertise, and wasn’t afraid to pose a few questions of her own during the talk-back.
