That would be incredible! Just give it time. I'm sure some of them will give in at the idea of getting lots of money, even if it's lower than some involved would like. Not to sound terribly prideful but I think the idea of an action figure of yourself would be really cool! People take pictures of themselves but how many people have action figures of themselves, let alone as a role in a famous movie you starred in?!
Sadly we might also have to wait for certain people's passing for their rights to be moved to someone who is willing to allow the production. By no means am I hoping for such a thing. I certainly hope the actors will allow for figures of their own free will.
