How it was made: the freeway scene in Deadpool→

fxguide:

Based on previs by Blur, production gathered background plates while filming in Detroit with a seven-camera RED DRAGON rig. Rothbart and DOP Ken Seng then devised a lightbox system for the greenscreen shoot. “We set up these LED panels all around the car using the Detroit plates,” explains Rothbart. “I lined them all up in the seven camera view and edited it so we had certain chunks we would use for each part of the sequence and then could map it out. For example, where the fight takes place in a tunnel, we had our tunnels loop. So the lights would dim, everything would go black and then it would come back to normal lighting as they come out of the tunnel. It meant that later on we got all that interactivity when we put the CG environment in.”

Very cool.
