I would look at the puppet and try and get as close to that as possible, like matting the fur down and making it look frozen (hairspray maybe) in some areas.
It is just a movie, maybe we all are taking this a little too serious, I think he did an outstanding job with everything he’s done so far.
It would be cool to see somebody complete a suit for a 8 foot man with 12 inch heel shoes, that would make him 9 feet tall. Get a few fans with some Hoth Rebel clothing and gear, and grab a camera and shoot something with the Wampa chasing them. All you do is add the special effects, some NEW shots of C-3PO and R2-D2, all you need are their costumes, as well as snowtroopers, stormtroopers and Vader.
Then, you can create something that was realized, but ultimately discarded due to it looking too fake, budget restraints and poor animation technology. You have the head of the Wampa now. Somebody make a fan film. I would do it myself, but, as we all know, it costs money, lots of money. I do know how I would shoot the film, and I would make the Wampa scary as hell too.
I’m sorry, but I would love to see a new scene with the Wampa. I know it will never happen, but, I get excited about this kind of thing. I know it can be done. This would be awesome to see.
