I just realized that there's been no casting news yet for Adam. Or maybe they're all under super-giant NDAs since the second one is filming?Huh, I thought I saw a four-armed alien.Filming of the untitled sequel began on August 10, with additional filming in the Downtown and Metro Atlanta areas, and Scotland. It is scheduled to last until July 2018. They are the first films to be shot entirely in IMAX, using a new 2D digital camera developed alongside Arri.
