When you’re on a sci-fi thriller like Extant, off-camera silliness is crucial. After all, you’ve got an isolated astronaut returning home after almost a year, an inexplicable pregnancy, misunderstood robots, government conspiracies, and a MURDEROUS ALIEN BABY… All of those things are basically my nightmare, so I completely understand the need to let loose whenever the cameras aren’t rolling.

Luckily, the cast of Extant seems to agree with me, as their new gag reel indicates! Take a peek at what goes on when the cast flubs dramatic dialogue, drops to the floor from a sucker punch, and grapples with the intense subject matter of a sci-fi thriller like Extant.

Don’t miss the Extant SDCC panel hosted by our own Chris Hardwick, this Thursday, July 9 at 12pm in Ballroom 20!
