Do people care what he thinks though? He played a dwarf in Narnia and a character making a joke of it with the Santas elf gag.
Here's an interview with Greg Doherty. He played a goblin in Harry Potter.
"Film work for little people doesn't come around too often, but when it does it's really enjoyable, which makes what Disney is doing so disappointing. I think they've gone backwards. What they have done is deny very talented and hard-working people with dwarfism that are out there and could have fulfilled these roles."
"You can see them in their interviews, on the streets; they aren't CGI dwarves, they're real people. There are many people that I know with dwarfism and this has upset them. By Disney doing this, they've gotten rid of those little people being able to have a chance for community in and around the shoots, and have basically said they don't need these people in the future."
If those rolls weren't available, Dinklage might never have broken out. One person doesn't speak for a community, that's all I'm saying. His view on it is no more valid than another with dwarfism.
