WAIT A MINUTE. Most Billys are cast as 12 year olds and then go do it for, sometimes, until they're 14. Elliott did it when he was 10 and left at 12 (when you're supposed to get cast)... I can see why he left earlier than most, 'cause damn I don't think he'd be a convincing Billy at 13, because puberty literally stretched him out.
Just superb. What a talent. But I had to LOL at 1.48 when the camera cuts to all those girls and women fanning themselves. Hot in there was it ladies? :)
