A boy named Jake Chambers is along for the ride, and the whole lot of them are looking to get to the eponymous Dark Tower. Roland Deschain, the last gunslinger, is chasing The Man in Black. That said, there are a few things we can say for certain based on trailers, posters, interviews and the like.

There’s no telling just how much the upcoming film might tackle. There are eight novels, more than a dozen comics and everything from It to The Stand to Salem’s Lot plays a part in King’s magnum opus. Both in terms of sheer amount of content as well as the themes and the narrative’s construction. The Dark Tower series by Stephen King is a lot.
