Cary Fukunaga quit 'It' because of disagreements with the studio.
The 'True Detective' director quit the remake of Stephen King's horror novel in May, just a few weeks ahead of it's production, which was due to start in New York.
The 38-year-old 'Jane Eyre' filmmaker said it was because New Line Cinema and him wanted to make "different movies".
He said: "[Writer Chase Palmer] and I had been working on that script for probably three years. There was a lot of our childhood and our experience in it.
"Ultimately, we and New Line have to agree on the kind of movie we want to make, and we just wanted to make different movies."
Cary went on to describe making films as "like a relationship".
He told Entertainment Weekly: "It's like a relationship: you can try to make the other person who you want them to be, but it's impossible really to change. You just have to work."
Although Cary has left his duties for 'It' behind, New Line are still progressing with the remake and 'Mama' director Andres Muschietti has taken over.
The film is not due to be released until 2017.
