After the previous season of The Amazing Race included a team of a deaf man and his mother, the current season, which had its debut last night in the States, includes Zev, a guy with Asperger's Syndrome who is racing with his best friend Justin. Since I live in Israel, I haven't seen anything from the current season, but I'm very curious about it.
Lately, it seems there's a spike in the entertainment industry's interest in autism, mostly in its Aspie form. Films such as "Adam" and shows such as "Boston Legal" and "Grey's Anatomy" have featured characters with Asperger's. The Amazing Race, as far as I know, is the first show to actually feature a real autistic person, and not just an actor playing one.
Good luck, Zev & Justin!
