20 Horror Sequels That Took FOREVER To Get Made

20. Doctor Sleep

There's one key reason that a sequel to Stanley Kubrick's all-timer horror classic The Shining took almost a full 40 years to get made - Stephen King didn't write it for over 30.

Indeed, the Doctor Sleep novel wasn't released until 2013, and though Warner Bros. began developing it the very next year, it was another five years before the Mike Flanagan-directed end product finally hit screens.

Despite the obvious risks posed by such a belated follow-up, the fact that King himself penned the sequel and it was left in the hands of a filmmaker as talented as Mike Flanagan sure didn't hurt - not to ignore a terrific cast led by Ewan McGregor and Rebecca Ferguson.

The nearly four-decade wait likely contributed to the film's failure to light a spark at the box office, though, because as beloved as The Shining is, do younger generations really think much about it at all?
