I'd love to see him in a Marvel movie., or in the upcoming Star Wars.
With so many characters and Marvel's talent at casting just the right actor for a role I'd love to see them find a spot for Tim Curry.
Ok maybe Marvel hasn't always gotten it quite right in the past but they are on a role lately and I'm sure Tim would be amazing as a villain I'm not thinking of.
I also think he'd make for a great villain in the upcoming Star Wars films as well.
