TheArnoldFans: Hi George, It's almost Christmas and I know your not a fan of the Star Wars Holiday Special but have you ever thought about doing an all new one? Maybe start from scratch?

George Lucas: "No, no way." (laughs)

TheArnoldFans: How far along is Indy 5?

George Lucas: "The next Indy film? Yes, we're working on it. It's in development. That's all I can say right now."

TheArnoldFans: FInally, where is Star Wars Celebration 5 going to be held? Do you have a location yet?

George Lucas: "Yes, official announcements will be made very soon."

Update: Star Wars Celebration V will take place August 12-15, 2010, at the Orange County Convention Center in Orlando, Florida.

Harrison Ford told France's Le Figaro (via People) that "the story for the new Indiana Jones is in the process of taking form. Steven Spielberg, George Lucas and myself are agreed on what the fifth adventure will concern, and George is actively at work. If the script is good, I'll be very happy to put the costume on again."

It's funny. I though Kingdom of the Crystal Skull (which I enjoyed) was the final Indiana Jones flick.
