We watched this film tonight as it was on ordinary broadcast channel. It is a 1980's film about an autistic man and was the first time most people had heard about autism at the time. It was really interesting watching the portrayal of autism that was broadcast to the public.
The main autistic character was said by a Dr to be very high functioning as he could talk (I know a lot of people do not like this phrase, but that was the language used in the film). The Dr said most autistic people are non-verbal.
Autism was presented as an extremely disabling condition which meant that those with autism would never be able to live independently. But it also introduced the idea that many autistic people had special talents. I know this latter point annoyed many people at the time who understood autism.
