Actually, Goldsman is rumored to have had a heavy hand in the final edit of the film. The film also largely resembles his version of the script.

What town do you live where they have well-lit sewers?

I might honestly go with Tim Reid.

He talks a bunch about doing this film here: http://junkee.com/trey-park…

The rumor came from a message board for parents of child actors, where contents of the script were discussed during Fukunaga's casting progress. The most telling post: http://imgur.com/QHHF6uU

Here's a scene from his script where Fukunaga reveals Pennywise let Al Marsh live as a child, so he could grow up to molest Bev every night & It could feed off of her fears:

'Lovecraftian' sounds like they're just going to continue ripping off It.

I was very impressed in his ability to stare himself down

Funny you say that, The Simpsons (seasons 1-3) was dubbed by the same team as the Real Ghostbusters. It was all the same voices and they improvised during the end credits as well.

He answered a question about seinfeld2000 in a previous AMA, and he's doesn't appear to be a fan:

Most exciting news on this project so far is Chung-hoon Chung being hired as the DOP.

Rumor has it Fukunaga wanted to keep the gangbang in and add a bunch of sexual stuff with all the kids that wasn't in the book. New Line Cinema wanted it out, as they weren't interested in making this NC-17 on a 30 million budget, but Fukunaga refused and walked.

I've heard he recorded about 6 episodes as the Joker, and Mark Hamill dubbed them over.
