Industrial Light and Magic has released this spectacular visual effects breakdown of the climactic space battle sequence in Rogue One.
The most impressive part to me is that massive lighting array they show, which I assume they use to shoot actors in X-Wings interacting with the space battle. A similar, much more elaborate rig, was used for Gravity. It’s cool to know that even for shots where you maybe see these pilots for maybe a few seconds each, they still put so much care into getting the look just right.
