I really didn't want to expand the negative vision of clowns because clowns are not intrinsically scary.
Pet Sematary' is one of my favorite books of Stephen King and I have a deep love relationship with it.
My approach to Pennywise was, on one hand, I wanted to stay true to the essence of the character but at the same time make it an edgier character that is basically unpredictable and people won't expect everything he comes up with.
Mythology is something that always has opportunities to explore. 'It' has been on Earth for millions of years. He's been in contact with humans for hundreds of years, every 27 years. So you can imagine the amount of material.
At the beginning when you're writing and building the beats of the story, everything that you put in there seems very essential to the story. However, when you have the movie finally edited and it's 4 four hours long, you realise that some of the events and some of the beats can be easily lifted but the essence of the story remains intact.
You have to go to what the essence of what Pennywise is about - the dark power of adulthood. It's not coincidence all the grown-ups in town are evil. This is not a story about a monster. It's a story about the end of childhood.
I'm very ambitious when it comes to cameos.
Everything that relates to Pennywise and Bob Gray is very cryptic, and it's like that for a reason. Probably the success of that character as a monster, as a villain is because of that crypticness and uncertainty that people have towards him.
The character of 'Mama' is so ambitious in a way that everything I did was always on the verge of being almost funny. So you have to be very careful with that. It's that sort of face that you don't usually see in horror.
