VIDEO : Bill Skarsgar Shares Biggest Difference Between Pennywise And Heath Ledger's Joker

...Bill Skarsgard embraced the role of Pennywise for this year's IT, but clarified with PEOPLE that his clown isn't in the same league as Ledger's, as Pennywise isn't even human.
?I think the biggest difference between Pennywise and the Joker character ? or at least Heath Ledger?s interpretation ? is that he?s far more based in reality,"
He added, "[The Joker] is sort of this social anarchist, crazy person, and I don?t think Pennywise is the same in that way. He?s not even human, he?s just pure evil.?
