Cirque du Soleil’s aerial artists will interact with 3-D projections on the wall of Petco Park as they stage the epic final battle from Kà during this year’s Comic-Con International in San Diego.

“It’s going to be something that people have never seen before, because we’re taking the projection and putting live artists into the projection,” says Jeff Lund, Cirque du Soleil company manager, in the exclusive video above.

Wired.com asked members of the troupe about the difficulties of interacting with 3-D projections, the challenge of performing such gravity-defying feats and the risks of re-creating Kà’s showdown between good and evil on a brick wall outdoors.

“They’re trying to take a vertical wall and make it feel like the ground, so that the audience gets this perspective of looking at a battle from above,” says battle coach Paul Cameron in the video interview, which includes a look at the massive 3-D undertaking.

If you’re in San Diego on July 21, you’ll be able to watch the battle from the streets across from the Omni Hotel just after sunset.
