I'm assuming that this post is in response to the recent Russell T Davies interview?
Several posters have mentioned discrimination within the industry (which I don't doubt exists), but from what I have read of the interview, Davies' statement was about authenticity. I read the interview in the Metro, so it may have been heavily edited, but I think this is the passage in question:
‘I’m not being woke about this… but I feel strongly that if I cast someone in a story, I am casting them to act as a lover, or an enemy, or someone on drugs or a criminal or a saint… they are not there to ‘act gay’ because ‘acting gay’ is a bunch of codes for a performance. It’s about authenticity, the taste of 2020.’
The "codes for a performance" bit is something that I find interesting. I am autistic and I would find it odd that in the name of authenticity only an autistic actor could play an autistic role. To me it implies that we are in some way homogenous.
If I was an actor, why would I be seen as more authentic to play an autistic character who (to cherry pick a few presentations) is non verbal, can make eye contact and has sound sensitivity, but no problem with smells, when I am verbal, have difficulty with eye contact, have only limited issues with sound, but have light sensitivity and quite severe smell sensitivity?
Would an autistic actor who didn't have the same presentations as the character they were playing also be using codes for a performance, or would it be okay because they may share some experiences with the character?
The above isn't about the Sia film by the way, which I've only just seen on here (and am about to go and read up on), it was rather a badly worded musing on what 'authenticity' means in an acting context.
