Katniss Everdeen is stepping out of the Hunger Games arena and into the Moonman-filled madness of the MTV Video Music Awards. At the VMAs on Sunday at 9 p.m. ET, MTV will debut the very first look at footage from “The Hunger Games,” the Jennifer Lawrence-starring adaptation of the best-selling dystopian novel. Up until now, we’ve seen photos of Lawrence as the arrow-wielding Katniss, plus glimpses of Josh Hutcherson as Peeta and Liam Hemsworth as Gale. But we haven’t yet seen “Hunger Games” in action. All that will change during the 28th annual VMAs, when Lawrence herself introduces the exclusive look, which will then be available exclusively on MTV.com … The first glimpse at the film, which hits theaters March 12, 2012, is just one juicy part of the pop-culture parade that is the VMAs. Get ready for performances from Lady Gaga, Bruno Mars, Adele, Lil Wayne, and Chris Brown, plus appearances by Jonah Hill, Rick Ross, Seth Rogen, Selena Gomez, Kim Kardashian and Odd Future. The 28th annual MTV Video Music Awards will air live Sunday, August 28, from the Nokia Theatre in Los Angeles at 9 p.m. ET/PT, following the Selena Gomez-hosted pre-show at 8.
