SET PICTURES: Ansel Elgort Shares Images of Green Screens on the Divergent Movie Set

Ansel Elgort (Divergent's Caleb Prior) posted these images from the Divergent set today. Pretty impressive looking green screen sets! Wonder what will be happening here.

Ansel: "#Divergent green screen. I walked into the studio and my mind was blown. I think it's like 40-50 feet high and wraps all the way around."
