Christopher from The Curious Incident of the Dog in the Night-Time - Paul Dano
Casting the part of a character with mental illness is always difficult, and The Curious Incident of the Dog in the Night-Time just happens to be one of the most beloved YA novels in recent memory for a lot of people. Paul Dano is the one actor who springs to mind that seems to have the ability to play such a nuanced and difficult character. He has already been a manic preacher, a depressed teen who has taken a vow of silence, and a mob hit man who gets in trouble with his employer. Christopher would be one more great role in an already impressive resume!
