Did You Know?
[on getting to know the real-life inspiration for the character of Charlie, a young adult adult with autism whom he portrayed in The Black Balloon
(2008)] From Sean I learnt to communicate physically with my hands and not use eye contact. Spending so much time with him I was able to really see the personality and the boundaries of autism that I could use.
For his role in the movie The Black Ballon, his role as an autistic boy, Luke stayed in character for 2 months, from the moment he woke up to the moment he went to sleep. His goal was to "Wake up autistic".
