Most people know Cary Fukunaga as the creative genius behind season one of the HBO hit series "True Detective." He directed every episode of the critically acclaimed first season of the anthology series, but he bowed out of Season 2, which did not meet the same critical acclaim.

His project that was highly anticipated in 2015 was a two-film adaptation of Stephen King's classic horror novel "It." But that also got halted when the director bowed out of the project. There wasn't much explanation at the time, but he recently spoke with Entertainment Weekly about the situation and revealed a few details as to why he left.

Earlier this summer, he walked away from the project for much of the same reasons others have left film projects. In the end, it was due to creative differences that he had with the studio, New Line Cinema.

This transition happened just before they were supposed to start production on the films, and he had already surprisingly cast young 22-year-old actor Will Poulter ("We're The Millers") in the lead role of the murderous clown "Pennywise."

This decision by the Fukunaga came after he had spent the past three years developing and writing the script with Chase Palmer.

"It's never easy," Fukunaga said. "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."

The director clashed with New Line about the kind of movie they wanted to make, and in the end, they would not allow him to use his own material.

"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," Fukunaga said. "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."

According to The Hollywood Reporter, the project is now moving forward with director Andy Muschietti ("Mama").
