Stephen King's classic horror novel It is being adapted into a two-part Warner Bros' blockbuster under the direction of Jane Eyre's' Cary Fukunaga. 

While the best-selling book was adapted into an ABC mini-series in 1990, Warner Bros picked up the rights in 2009 to adapt the book into a feature length film, according to the Hollywood Reporter. 

The script is being co-written by Fukunaga and Chase Palmer, who adapted Herbert's Dune for Paramount. 

King's 1986 novel tells the story of a group of adults know as The Losers Club, who reunite in their hometown of Maine, where they encounter an evil child-murdering clown named Pennywise. The story jumps to and from the past as the group remembers their childhood days where they were faced and threatened by him.

The chilling story told through the mini-series adaption was a hit, starring Tim Curry as the evil clown and John Ritter, Harry Anderson and Richard Thomas.

The new Warner Bros. adaptation has been in the making for years now, but a recent update from screenwriter David Kajganich has revealed that the filmmakers are having trouble fitting the 1,138 page novel into a two to three hour film. 

The original mini-series spanned over a total of three hours and did not do justice to the gruesome and adult content of King's book, according to 

A two-part film will give room for the filmmakers to fully split between parallel running-events and narrative threads. 

This isn't the only Stephen King adaption that is in Warner Bros' works. The Stand, spread over 1,000 will be headed by Ben Affleck, according to 

David Kajganich has been hired on the script of The Stand, but it's unclear whether Affleck will contribute on the writing or directing of the film.

The post-apocalyptic supernatural book is divided into three parts: Captain Tips, On the Border and The Stand, which could again be a struggle to squeeze into a three hour film.
