King was never a fan of Jack Nicholson’s casting as Jack Torrance – but Nicholson becomes that character, or that character becomes him. King was always of the belief that Nicholson brought too much insanity to the table before Torrance lost his mind. The book and the film exist in two different states, and if you want to see a literal translation of King’s novel, then there is always the 1997 television mini-series (which King prefers – even though it feels very cheap).
I just discovered that the US version of The Shining is longer (at 144 mins) than the international cut (119 mins). That’s something that I’m going to have to check out.
