Fighting aliens is hard work, and sometimes you just need to let off a little steam.

That was no doubt part of the inspiration behind a candid moment captured recently on the "Independence Day Resurgence" set, as returning star Jeff Goldblum, posing in front of a spacecraft, was photobombed by co-star Liam Hemsworth. The goofy snap, which Goldblum shared on his new Facebook page, gives fans yet another a glimpse at the playful nature that's part of the film's production, and offers hope that the hotly-anticipated sequel to 1996's "Independence Day" won't take itself too seriously.

So there I was thinking about how I would save mankind when this guy photobombs me. Oh, why hello Facebook, nice to finally meet you. #IDR

"Independence Day Resurgence" picks up some 20 years after the first flick, and centers around Earth's prep for yet another alien invasion, as the distress call from the last batch of attackers has only just now reached their home planet. Goldblum is suiting up again as scientist-turned-savior David Levinson, while Hemsworth's role is undisclosed for now. (Judging by the above photo, perhaps he plays Goldblum or Bill Pullman's mischievous son?) And traveling to the moon is apparently part of the plan, too.

Joining Goldblum and Pullman are fellow returnees Vivica A. Fox, Judd Hirsch, and Brent Spiner, among others. On Hemsworth's newbie team are Sela Ward, Charlotte Gainsbourg, Jessie Usher, Joey King, and Maika Monroe.
