Most TV producers use neurotypical actors or actresses due to circumstances that aspires can't handle pressure.
Being an actor or an actress is apparently suppose to be a very high pressure job and most aspires wouldn't handle it.
That's why neurotypicals takes on the aspie roles instead of getting an aspie to do it.
I agree that some would struggle to handle the pressure, but there are also most definitely autistic people who could and in fact do...
For instance look at wildlife TV presenter Chris Packham who has been in that job for approx 30 years, since he was often presenting shows live such as
Earth Live there's no chance for 2nd takes and he's got to get it right the first time, so in some ways this is even higher pressure than being a TV series or movie actor:
Chris Packham on living with Asperger's: 'I’ve spent 30 years on the telly trying my best to act normal'
Chris Packham told the world about his autism in a BBC TV documentary called
Asperger's And Me last year and continues to be an inspiration to people with autism.
Did you know that actor Dan Aykroyd who was in the star cast of
The Blues Brothers (1980) and the original
Ghostbusters (1984) movies was diagnosed as having mild symptoms of Asperger’s syndrome? He didn't admit openly that he had autism until 2004:
Dan Aykroyd - AUTISM WIKI
I have saved my best example until last.
Sir Anthony Hopkins CBE has a long career starring in numerous movies and TV shows since 1960. He is currently staring in the hit television series
West World which is in it's 2nd season at the time of writing. He was diagnosed with Asperger's syndrome when he was in his 70s and is showing now signs of slowing down even at 80 years old, he is currently filming for a new movie called
The Pope (2018) that is due to be release in November this year on Netflix where he is playing the starring role of
Pope Benedict, it's not personally my sort of movie, but I'm sure some people will enjoy it and you can guarantee that the acting will be first class as always. He is probably most well known for his portrayal of
Hannibal Lecter in
The Silence of the Lambs (1991) and also in
Hannibal (2001). He is in my opinion one of the finest actors ever born:
Sir Anthony Hopkins CBE said:
"There are many positives that can come from the sometimes unusual characteristics often found in those with Asperger’s. ‘I don’t go to parties, I don’t have many friends,’ he said. ‘But I do like people. I do like to get inside their heads. ‘I definitely look at people differently."
These are just a few examples out of many.
