James Gunn's post-'Guardians of the Galaxy' mystery movie is finally revealed

Before James Gunn brought into the world his entertaining vision of Marvel's Guardians of the Galaxy — and was unceremoniously dumped by Disney following a bad faith character assassination — he made horror movies. Good, messed up horror movies like Slither.

In the time since his Disney separation, noisy speculation has been building around Brightburn, a Sony Pictures release that reunites Gunn with Slither star Elizabeth Banks. But what is it? Many have guessed that Brightburn is just a codename, and Gunn has been working on a video game adaptation.

Those people were wrong. The first trailer for Brightburn is here, and it looks like Starman meets Species: creepy outer space kid found and raised by baby-obsessed husband-and-wife but he turns out to be some kind of death-dealing monster. Sign us the hell up.
