Booth is holding a bottle of brandy labeled Crimson King Imperial Brandy; label has the red eye and spider.

Dick Hallorann appears in The Shining and in It, and of course It has multiple connections to DT.

Mother Abigail in The Stand makes a subtle reference to the power known as shining ("My own grandmother used to call it the shining lamp of God, sometimes just the shine." )

The first introductory quote in The Shining is from Edgar Allan Poe's "Masque of the Red Death". In The Dark Tower VI: Song of Susannah, Mia mentions the "Red Death" plague and Susannah forms the connection to Poe's short story.

After Wendy has locked Jack in the pantry and Danny is asleep in the bedroom, she takes 19 steps downstairs to check on Jack. Does anyone think that the Overlook is a modern thinny? ?

The bartender in Silver Bullet has a bat named "The Peacemaker", as does the bartender in Hambry from Wizard and Glass.

"The Raft" definitely contains a connection to Dark Tower. It appears that, much like The Mist, something from Roland's world has come through to ours. An image of the man-eating blob was what came to my mind the instant I read about an army of men devoured in the thinny outside of Mejis.

During the first short story about the mist, the character considers the signs of going crazy, among which is "A rose beings to sing". It's a bit obscure, but I feel like that's a mention. Page number is not exact unfortunately.

Now, I am not sure if this is a stretch, and I only include it because R.F. is also Walter in The Dark Tower series. In The Stand, R.F. gives black rocks, which in some cased are also things the person really needs. You may already see my connection here. After giving them these needed things, he has this power over them... Needful Things.... Sounds very familiar right? I know it is not exactly the same, but very very similar.

Mother Abigail refers to Frannie's unborn baby as "The Chap". I believe in "Wolves of The Calla" when Susannah was with child, it was really the Dark Man's offspring she was to give birth to. Her alter ego, Detta, referring to him as "The Chap" as well, his destiny to kill Roland.

character name is Barry Dorgan - similar to Dogan. Reminded me of Callah and Callahan. In the Dark Tower series. Read the book years ago but spotted the name whilst watching the movie.

In the short story "Rita Hayworth and the Shawshank Redemption" there is a raven named Jake. In The Gunslinger, we meet a raven named Zoltan, and then we meet Jake. Also, Andy Dufrense's prison number adds up to 19.

The villain in Storm of the Century is named Andre Linoge.  It is pointed out in the book that this is an anagram of Legion, which is the true name of the Ageless Stranger according to Walter at the end of the Gunslinger.

Also, on a smaller scale, the townsfolk of Little Tall island tend to use radio channel 19 to contact each other.

Legion is referenced in this movie and at the end of the gunslinger.

There are MANY connections possibly showing that Andre Linoge very well may be Randall Flagg. 1. Both are Wizards with no remorse in killing humans. 2.Linoge wears the clothes of a regular guy, especially the jeans, the same as Flagg. 3.Linoge is a anagram for "Legion", a term Flagg has used for himself before. 4.Linoge, the same as Flagg, has a wild temper flair when something doesn't go the exact way he wants it too. 5.Linoge apparently walks into town, with a walking cane. Flagg is well known as the walking dude. 6.Both sit in the Indian style position. 7.Both use dreams to convey messages. 8.Both turn a woman's hair white when they have contact with her. 9.Linoge shows himself as a young man, a old wizard, and as a beast (Teeth). All of these can be lies and not his true form. Flagg also shape shifts at will. 10.Both use natural disasters to begin their activities. (Much like Pennywise) 11.Linoge uses the term "Dimmer" when pretending to be the Newscaster. Flagg is well known with this term/name. 12.Linoge and Flagg both know the bad things people have done and what they are most ashamed of. 13.It is said that since the Tower books never mention Flagg dying, and Linoge did, Linoge could have been lying about that. Also it is said that the boy he takes is never mentioned. It's possible Flagg kept it a secret. Obviously Linoge was very concerend about keeping it secret. Why? No one would have believed the town people anyway. Is it possible Flagg raised a son to look, act and speak like him? Maybe to sacrifice to Mordred? It would certainly make it easier for him to go about his business if he was presumed dead. Also it ties in with Linoge needing the boy to be a complete secret. In summerizing, it seems very possible that Flagg may have lived on and gained his entry into the Tower after Roland. It was after all, his chief concern. And with Mordred and the Crimson King dead, and Roland occupied...who could have stopped him?
