"But it is an important conversation to have, not just about this movie, but as a whole — about representation."
She continued: "For me, when I hear that there's anybody that feels left out I feel terrible. It's an ongoing and important dialogue to be had, about neurotypical actors portraying neurodivergent characters. It is an important one to have with people, with experts and who know how to engage in the conversation. I encourage it, truly. I think it's important to say that we are listening."
Sia previously defended the film after critics were upset when she released the trailer on Twitter that she wasn't doing the autistic community justice.
In response to one person's tweet, Sia hit back with: "I cast thirteen neuroatypical people, three trans folk, and not as f**king prostitutes or drug addicts but s (sic) as doctors, nurses and singers."
She continued to respond to others, including one who wrote: "Several autistic actors, myself included, responded to these tweets. We all said we could have acted in it on short notice. These excuses are just that - excuses. The fact of the matter is zero effort was made to include anyone who is actually autistic. #NothingAboutUsWithoutUs."
Sia replied, "Maybe you're just a bad actor."
Not long after the Golden Globe nominations were announced, the singer is said to have apologised for including a scene in the film in which Ziegler's character is restrained in a way that could be harmful for autistic people.
