[on preparing for his role as a young adult with autism in the Australian film
The Black Balloon (2008) by, among other things, strapping his legs to develop the rigid gait and stiffness that is a trait of some people with autism] I didn't research "What is autism," as it was not relevant to my character. I wanted to know more about the physical and mental elements that my character was and was not capable of; for instance the rigidness, the lack of eye contact and the lost world. I wanted to understand the general physical side of autism.
