X-Men’s Simon Kinberg didn’t mean to start a war.

After finishing main unit filming on X-MEN: APOCALYPSE and visiting NYC and The Hamptons for some R&R, director Bryan Singer made his way back to Montreal for editing his masterpiece and overseeing the final weeks of second unit filming. He recently instagrammed this photo of writer/producer Simon Kinberg having fun on the 1983 Pentagon War Room set, surrounded by green screen. This setting was briefly shown in 1962-set X-MEN: FIRST CLASS.
