Inspector Lewis Sunday night (on PBS), featured a character, an Oxford student, who had Asperger's. The character reminded me very much of Ian Mackenzie! He never looked straight into anyone's eyes, he knew what time he arrived anywhere to the exact minute and how long he stayed, was an artist who could draw anyone rapidly after a quick glance, he knew the social things he was "supposed" to do, but didn't really understand or much care why, and he was the master of the nonsequiter. The actor who portrayed him did a wonderful job. The character gets a lot of air time, and it was a good mystery.
You can watch the show online until September 13:
