We've been blasting you all week with "Avatar" updates, and now the day is finally here. This afternoon, at 3pm EST/12pm PST, director James Cameron and stars Sam Worthington and Zoe Saldana will sit down to answer questions put to them by fans on MTV and Facebook. The event will be streamed live on the MTV.com Movies homepage. In addition to having all of those burning questions you might have about the 3-D mega-blockbuster answered, you'll also get to see a little slice of the movie thanks to an all-new clip.
While "Avatar" fans have much to look forward to this afternoon, there's more to come from MTV before the movie hits theaters on December 18. Soon, before that date, the latest episode of "Behind the Screen" will air. The centerpiece for this new episode will be "Avatar," with exclusive interviews, behind-the-scenes footage and clips to hype you up for the coming release. Get psyched, people.
