The Distinctive Baritone said: "From the way Christopher was portrayed onstage in the Broadway production, I would say that in the stage version at least, he is a little further on the spectrum than Asperger's. I would say that Christopher has full-blown autism, but is "high functioning."
According to Wikipedia, Asperger's Syndrome - in the way we regard it today - did not become something that was really understood and diagnosed until the 1980's, and I don't think it was something people were widely aware of until around the new millennium, so at least in terms of plays that have been widely produced, I guess it hasn't really been given a "chance" yet. As autism awareness grows, I imagine we will see more characters who are written as having autism.
However, there are probably MANY characters in dramatic literature that could be interpreted as having undiagnosed high-functioning autism or Asperger's, such asAlan inEquus,Michael inThe Pillowman,and Georges Seurat inSunday in the Park with George."
I had never considered Georges or Alan in terms of Autism (unfamiliar with The Pillowman), but I think that interpretation makes a lot of sense, and it opens up my mind in terms of ways to interpret them. Thanks!
