It’s clear that there’s a lot of crazy stuff going on in Noah Hawley’s new FX X-Men show Legion, but you might not even realize just how crazy it is until you see the behind-the-scenes video that the network released today. The clip is primarily concerned with the show’s sets and the literal “world” of Legion, and it’s cool to see the little tricks that Hawley and his production crew have set themselves up with—like a dynamic lighting system that allows them to change colors and brightness on the fly.
