'Elysium' Trailer: Matt Damon Isn't Being Sarcastic (VIDEO)

What's labeled as the fourth trailer for "Elysium" has debuted online -- this one clocking in at over three minutes in length, something that's probably in opposition to what director Neill Blomkamp would prefer.

"I try to show as little as I can," Blomkamp said during an "Elysium" presentation back in April (. "The thing is, if you're a responsible, functioning filmmaker in the 21st century, you can't spend a hundred million dollars and then try to behave as though you're going to keep [the movie] wrapped under a blanket ... I realize that you have to get it out there."

That's exactly what this trailer does, laying out the film's plot and teasing some big action set pieces. Watch above -- or don't, if you want to remain unspoiled. (OK, one spoiler: Someone says, "Bring down the bone saw.")

Matt Damon, Jodie Foster and Sharlto Copley star in "Elysium." The film is out on Aug. 9.
