UPDATE: If you want to catch the last few minutes, it works marginally better on MTV itself.

The countdown is on as we approach the final days of Avatar marketing. Right now (3:00PM EST), Cameron, Worthington, and Saldana are discussing the film via a live online chat hosted through Facebook.

If you care to participate, head here (I assume you need to be logged into facebook, but you can give it a shot either way). I don’t know how smoothly this is going to run*, but if you’ve got the time or inclination, have at it.

*Apparently not smoothly at all.

Ask Cameron if there will be blue tits, then report on the MESSAGE BOARD
