I work with a hearing company just entering our second year in residence at a Deaf school, and part of our residency agreement is that we cast students in our professional productions. Our attempts at being accessible for Deaf actors and patrons has led us to begin working with actors who have other disabilities as well. In my last show with this company we had a legally blind actor (let me tell you - it's really quite scary being the one on deck to hand off a rifle with bayonet to a guy who can't see it) and in this next one we've got a Deaf student actor who is also physically disabled. Actually, we're doing an adaptation of a Christmas Carol and he'll be playing Tiny Tim. We can't get around the fact that he has difficulties walking, but we might as well give him a chance to use what he's got, rather than casting an able-bodied person as a character who is disabled!
