Matt Damon is kicking things back into high gear.

After proving his chops as a credible action hero in the first three "Bourne" films, the "Behind the Candelabra" star is back in tough guy mode once again with "Elysium," director Neill Blomkamp's highly-anticipated follow-up to the 2009 sleeper hit "District 9." Now a superb, extra-long second trailer has been released for the futuristic sci-fi, and it features more plot (a sickly young girl figures into the setup this time), more action and, yes, more robot humor. Is August 9 here yet or what?

My grade for the trailer: A-. After watching it below, rate it for yourself at top left.

Official plot synopsis:

In the year 2154, the very wealthy live on Elysium, a massive high-tech utopian metropolis located in the skies above earth that is free of crime, war, poverty, hunger, and diseases, while everyone else lives on an overpopulated, ruined Earth below. The citizens of Elysium live a life of luxury while the citizen of the Earth struggle to survive on a daily basis and are desperate to escape the planet, but those who maintain Elysium will stop at nothing to enforce anti-immigration laws and preserve their citizens' lifestyle. Terminally diagnosed with cancer, 36-year-old Max DeCosta (Matt Damon), is in desperate need to get to Elysium to be cured and he reluctantly takes on a dangerous mission which pits him against Elysium’s Secretary Delacourt (Jodie Foster) and her forces.
