The James Cameron-produced “Cirque du Soleil: Worlds Away” isn’t a horror movie, but we’re told filming it was scary. “When you see this without the music, the guys yell and shout and talk to each other and occasionally swear,” director Andrew Adamson told us at Regal E-Walk 13. “You see someone 40, 50 feet in the air swearing, you don’t know if that means, ‘Ouch, I hurt my hand,’ or, ‘Ouch, I’m going to plummet to my death.’ So that was terrifying.” Later, we’re told, guests including Adamson, Cameron and Heather Graham celebrated at Jezebel SoHo. Jet Tim Tebow also popped in to congratulate a producer who we’re told is his godfather. The film opened Friday.
