Dwayne Johnson's Zipping Quality in the Film

"It works like I was happily sitting there eating my popcorn, you know, smiling," he said. "But if I was to stop and analyze it, I'd be like, hang on a second." The audience needs to know where he's zipping too because of the laser-like effect - but by the same token, he should be able to get there in under a frame. So we made it a little bit more streaky just so you could see where direction he's going from A to B".
