Later on tonight, during Jimmy Fallon's second night as host of 'The Tonight Show,' the full first trailer for the upcoming 'Guardians of the Galaxy' movie will be unveiled. But you just knew there'd be a sneak peek before then, right?

The 15-second sneak-peek trailer for the movie's official trailer (follow all that?) doesn't offer much in terms of plot or anything like that. But it looks like it's going to pretty much follow that knockout path paved by other Marvel movies of the past few years, like the 'Iron Man' and 'Thor' films and the almighty 'Avengers.'

'Parks and Recreation' star Chris Pratt is at the center of the brief trailer, with some cool CGI whizzing by here and there. While we'd love to see more of the talking raccoon (who wouldn't?), we're guessing there's gonna be a whole lot more of him in tonight's clip.

And it looks like no expense was spared on the movie, which hits theaters on Aug. 1. It's kind of a gamble for Marvel, since 'Guardians of the Galaxy' doesn't have the name-brand appeal of the usual comic-book heroes.

But with a cast that includes Bradley Cooper, Vin Diesel and Zoe Saldana -- plus all that sweet, sweet CGI -- the "action-packed, epic space adventure" (the studio's words) will most likely dominate movie screens when it premieres this summer.

While you wait for tonight's unveiling of the full trailer, you can keep yourself busy by checking out another new video clip from Marvel -- this one for 'All Hail the King,' a short included in the 'Thor: The Dark World' home video that comes out next week. It's all about villain the Mandarin's fate behind bars. Here ya go:

UPDATE: The full trailer is now available. You can watch it below.
