"Genuinely Was Not Prepared For Him To Be That Good" – 17 Acting Performances That Took Us Totally By Surprise

"I grew up watching him in films but obviously only the kid/family-friendly stuff. The first time I saw him in a serious role was probably One Hour Photo and it was like whiplash. 

Gone was the funny, charming, slightly goofy man I knew and replacing him was this sinister, foreboding character that frankly terrified the pants off of me. I've since gone back to watch more of his stuff and the man's range is impressive. Good Will Hunting, Dead Poets Society, his guest appearance on Law & Order: SVU – we lost such a talent with his passing."
