A new TV spot for Marvel's Guardians of the Galaxy debuts some unseen footage from the upcoming space opera — and perhaps suggests how Chris Pratt's team of unlikely heroes ended up responsible for the universe after all.

Earlier trailers for James Gunn's summer movie have shown Pratt's Peter Quill, Zoe Saldana's Gamora, Dave Bautista's Drax and the team of Rocket Raccoon and Groot (voiced by Bradley Cooper and Vin Diesel, respectively) in custody and saving the universe, but the new 30-second spot suggests that there might be a link between those two things.

"Our world is facing an unstoppable threat," Glenn Close -- playing Nova Prime Rael, leader of an intergalactic police force -- says in the ad. "Send in the Guardians." Does this suggest that the only reason our new heroes are going to save the day is because they're being sent on a suicide mission by the authorities? (Shades of DC's Suicide Squad, if so.)

The ad also debuts Pratt announcing the movie's title in his best Burt Macklin voice, although fans of the trailers to date may miss the use of a classic-rock track this time around.

Guardians of the Galaxy will be released Aug. 1.
