As you might suspect, lots of folks have been pointing me at bootleg videos on the net of the test reel Disney showed of the TRON sequel/remake/whatever, titled TR2N. I'm truly impressed by what I saw. The world inside the computer seems to be faithful to the original vision - in particular, they appear to have resisted the temptation to make it more real-world - while updating the graphics to something that folks used to modern computer games won't sneer at.
I'm especially intrigued by the little bit we see of Jeff Bridges. In the original, Kevin Flynn is a good guy. Now? We're not so sure. That will be a very interesting switch if it pans out.
To answer the inevitable questions: Nobody's asked me to participate yet. If they do, I'm there.
