Ok, that's not what you were looking for, and I could never even come close to being able to afford to buy TRON - no matter what price they sold it. But in my hands, I'd certainally put forth a worthy sequel... well, if I could afford the production costs of that too.
I've long envisioned a particular kind of TRON sequel that could retain all that we loved about the original TRON and also open up all the new possibilities of modern computing. I would love so much to see my take on this made in to TRON reality!
Of course, I'm sure every other TRON fan with an idea would like to see their idea on the big screen as well.
You know what I think a great (realistic) formula for making a TRON sequel would be, IF Disney were to sell it? Sell it to Mr. Lisberger himself. I bet he could round up the necessary forces to bring his TRON ideas to life.
