Liam Hemsworth brought the heat, literally, to today's MTV Movie Awards in LA. He took the stage, which was lit with flames, to present the first teaser for Catching Fire. The clip showed Liam, Jennifer Lawrence and Josh Hutcherson in their Hunger Games characters and also revealed a peek at Philip Seymour Hoffman as Plutarch. Jennifer wasn't on hand for the show, and Liam's brother also missed out on a big night. Chris Hemsworth and his Avengers co-stars won movie of the year, but Chris was unable to attend since he was busy travelling back from the Caribbean, where he witnessed Matt Damon's vow-renewal ceremony over the weekend.
