The assistant principal, Mr.Morton, randomly takes on a John Wayne expression, just like a cerrtain evil train in The Wastelands.

Estelle Horan's doorbell rings the tune of "Hey Jude" just as was played on an ancient piano in Tull in The Gunslinger

In the book Cell, there is a character named Alice, much like the Alice in the town of Tull from "The Gunslinger". Later on in Cell, a couple guys in an SUV drive by and toss a cinder block which strikes Alice in the face, nearly caving her face in. Now as you might recall from The Gunslinger, Alice had a huge scar across her face. Cell was the first book by Stephen King that I read, and The Gunslinger was my 2nd, so i immediately made that connection.

The reference to Charlie the Choo-Choo (the ride) is apparent as the Raggedy Man's clothes hang at the end of Cell. Charlie the Choo-Choo is also the name of the book that Jake receives in book III (The Wastelands) of the Dark Tower series describing a soon to meet, Blaine (the pain).

The phone number 207-919-9811 becomes 9-19-19 when you add it up, which thanks to DT I do with everything now. Thanks Steve! lol!!!

Clay is drawing the Raggedy Man, and has a lot of trouble drawing his eyes, the same as (i forgot his name) the kid with his tongue ripped out who draws amazingly had with the Crimson King. Also RM's Harvard hoodie is red (possibly the Crimson King at work in yet another dimension?)

I think Clay's series Dark Wanderer, who's main characters are listed on page 19 (in the hardcover edition) are our own Dark Tower heroes. The titular characters name is Ray Damon (R.D.). I think Clay's series is his vision of our Dark Tower series.

The plane that crashes on Boston Common has tail number LN6409B. 6904 adds up to 19. L = 12, N = 14 = 5, B = 2 12 5 2 = 19. I know that one is a stretch, but still :)

On page 26 of Cell, of the scribner hardcover edition, there is a plane crash. The tale number on the plane reads LN6409B.. the numbers adding up to 19. And at the moment this takes place, things have become very "19"

When Jordan suggests going to the gas station to prepare to torch the Gaiten flock, the Head says, "He's talking about the Citgo." This is similar to the Citgo oil pumps in Wizard and Glass.

When the characters in Clay's comic "Dark Wanderer" are described, a character named "the Wizard Flak" is mentioned, which is possibly a play on "Flagg" Also, the Dark Wanderer himself is called Ray Damon, with the same initials as Roland Deschain. Roland could often be seen as a "Dark Wanderer" in my opinion.

charlie the choo-choo is mentioned as a kiddie ride, and the remains of the raggedy mans sweatshirt is draped across the rides ticket booth. I was thinking that this my indicate that the cell phone pulse may have been caused by the sombra corp and this is the story of how this perticular world had "moved on".

Near the end of the book, after beginning the search for his son, Clay sees an unfinished Charlie the Choo-Choo ride in the park where they were being held captive.

I had to search for the page number since I listen to most books as audio books. The reference to the Dark Tower I found near the end of the "Cell". A comment is made that the ride "Charlie the Choo-Choo" was seen set up at the Expo in Kashwak. I know it is a stretch of a connection, being that Charlie the Choo-Choo was a character in a book that was used in the Dark Tower. Charlie the Choo-Choo being Blane the mono.

There is a half constructed childrens ride in Cell called Charlie the Choo Choo. It is the same name of a childrens story that Jake Chambers sees in the Manhattan Restuarant of the Mind and is symbolic of Blaine the insane train.

The main character in Cell is a graphic artist who seems to have made a comic book series that is very similar to Roland from the Dark Tower.

I made an immediate connection to the Dark Tower and other connected books. This would explain the mystery that is the central theme of the novel, of how in six hours James Cogan of Nederland, Colorado arrived in Moose-Lookit Island, Maine. Also when he mentions going to Starbucks that didn't expand outside Seattle, Washington until 1987. This is a man who has passed through doors to Roland Deschain world, that is probably were he left his coat tie and wallet and how he ended up with a Russian coin in his pocket. I think if Stephen King ever revisits the Dark Tower universe that the other side of the story may be told.

If you go with non-book connections, the television series Haven, based on The Colorado Kid, mentions Shawshank. That would bring The Shawshank Redemption into the Dark Tower world. The Tommyknockers, the miniseries, is based in Haven.
