Production officially got underway on Deadpool 2 this week, and Josh Brolin couldn’t wait to show us what he’s undergoing to become Cable.

While Ryan Reynolds has already posted a photo from the set, Brolin shared a picture on Instagram in which a mold is being taken of his face to prepare the prosthetics needed to alter him into the time-traveling mutant warrior.

Brolin wrote in the caption: “Insanity on the brink. Face is morphing into something machine, fierce, hair sliced, arm machined, bulged. W is Deadpool?!? Looking. Looking. All I got are these two…molding me, prodding, turning me into something hard.”

Brolin, of course, has a foot in two Marvel universes, not just portraying Cable but also performing as Thanos in the upcoming Avengers: Infinity War, although he’s mostly in a motion capture suit for that gig.

Not to be outdone, Deadpool himself posted his own photo on Wednesday in which he is seen with new cast member Julian Dennison.

Deadpool 2 is set for release on June 1, 2018, and we expect lots more to come on social media between then and now.
