The trailer opens with a castle over-looking a small town shadow. This could just be your run-of-the-mill Mid-World castle and town, but if we had to bet (and judging by other story details and hints in the trailer), we’d put money on this being Algul Siento.
Algul Siento shows up late in the book series and is a prison for the Breakers, a group being forced to work for the Man in Black and The Crimson King to bring down the Dark Tower.
Shortly after, we are introduced to Jake Chambers (Tom Taylor) who dreams of the Tower, Roland (Idris Elba), and the Man in Black (Matthew McConaughey). Jake wallpapers his room with drawings of them, as well as drawings of the Breakers. Who are these Breakers?
In the books, the Breakers are people with powerful psychic abilities who are imprisoned by the Man in Black. Their abilities are harnessed to bring down the Dark Tower by destroying the beams holding it up.
The Dark Tower and the beams
This shot shows the beams holding up the Dark Tower. The Tower is essentially the cog at the center of all existence, with the beams serving as the spokes. Destroy enough spokes and the cog falls.
The Dark Tower
A shot later in the trailer is almost certainly the concentrated psychic energy of the Breakers hitting one of the beams.
The Overlook Hotel
One of the most interesting things about The Dark Tower series is that it manages to incorporate many of King’s other works into the story in both large and small ways. One of the first easter eggs from the film shows a framed photo of The Overlook Hotel — the haunted location of “The Shining” — sitting on the desk of a psychiatrist Jake is talking to.
The House on Dutch Hill
Jake’s visions eventually lead him to the House on Dutch Hill (a location from “The Wastelands,” the third book in the series) which isn’t your ordinary house. The House on Dutch Hill is actually a portal to Mid-World and to Roland. Getting through the portal isn’t as easy as just walking through the door though…
The Doorway Demon
This is almost certainly the Doorway Demon that guards the portal in the Dutch Hill House. The demon is actually the house itself, which comes alive to try stopping Jake from getting to Mid-World.
The other big easter egg that pops up in the trailer is a reference to another of King’s most popular novels: “It.” A blink-and-you-miss-it scene shows Jake stumbling across some sort of carnival with a sign that reads “Pennywise House of…” Pennywise is the clown that terrorizes the town of Derry for the entirety of “It.” There is also a hand coming out ground holding balloons, a particularly favorite item of the clown to scare his victims.
There are a couple different things these evil looking beings could be. One option is the Slow Mutants, humans exposed to pollutants that caused them to mutate. The other option — the one we and the internet seems to be leaning toward — is that these are the Taheen.
The Taheen are able to take many forms, ranging from everyday people to humanoid with animal heads, and essentially serve as henchman for the Man in Black.
The Man in Black
The Man in Black himself is worth a separate analysis. The MIB is trying to bring down the tower and is someone Roland considers to be “worse” than the devil. He goes by many different names including Walter Padick, Richard Fanin, and Randall Flagg, and appears as the primary antagonist in other King stories like “The Stand” and “The Eyes of the Dragon.”
The incredibly powerful MIB and Roland have a long history that spans back to Roland childhood, but he won’t be the most dangerous thing the gunslinger faces on his way to the Tower.
All Hail the Crimson King
The Man in Black may be a constant in Roland’s life, but it’s The Crimson King who is pulling the strings and is the true antagonist in the series. Essentially, the MIB is Darth Vader and The Crimson King is the Emperor.
In the books, the MIB wants to bring the Tower down because, as if be the center of all existence wasn’t enough, it is also imprisoning The Crimson King.
There is a scene in the trailer that shows Jake coming face-to-face with some kind of red mist. Our guess is this is a thinny.
In “The Dark Tower” series, thinnies are areas where reality has eroded away. They can draw unsuspecting people into them by emitting a hum.
We get a quick glimpse of a younger Roland being comforted by his father Steven, played by Dennis Haysbert. If plans for “The Dark Tower” TV series — which would fill in the gaps and backstory of Roland — come to fruition there’s a good chance we could be seeing more of Haysbert as Roland’s stern but loving father.
The Gunslinger’s Oath
The trailer ends with Roland doing some fancy gun-work while teaching Jake how to wield his guns and recite the Gunslinger’s Oath.
