Literally the 7th book in the Dark Tower by Stephen King
Oh yeah, the Spiderman saga right after the Quidditch saga. What the hell was Steven King on
Cocaine. Mountains of cocaine.
That’s just it - he wasn’t!
The Gunslinger (genuinely one of the greatest books I’ve ever read) was written on mountains of cocaine.
He was clean for the Dark Tower sequels
Probably why the last 3 were so meh. But goddamn that ending.
Cujo was written on so much coke that king doesn’t even remember writing it. The only book of his that really never did it for me.
Random bit of trivia about the film:
https://en.wikipedia.org/wiki/Cujo_(film)
Cujo was played by four St. Bernards, several mechanical dogs, and a black Labrador–Great Dane mix in a St. Bernard costume. In some shots, stuntman Gary Morgan played Cujo while wearing a large dog costume.
He explains that in those books too.
