Earlier this week it was revealed that the first footage from The Dark Tower will debut in October during Entertainment Weekly’s Popfest. Until then, Stephen King and the cast of the long-awaited adaptation have been releasing intriguing teaser photos on social media — like the latest image, which features young protagonist Jake Chambers and a quote that fans will immediately recognize.

The new photo from The Dark Tower popped up on Stephen King’s Facebook page and was also shared by newcomer Tom Taylor, who plays Jake in the upcoming film:

Fans of King’s epic novel series will recognize that quote as something Jake says to Roland during a crucial moment in the first book. The full quote is actually, “Go, then. There are other worlds than these.” But as director Nikolaj Arcel has confirmed, the film adaptation is actually more of a sequel, offering a great new-ish story for book readers and newbies alike.

The Dark Tower stars Idris Elba as gunslinger Roland Deschain, who embarks on an epic quest to reach the titular tower before The Man in Black and the nefarious Red King can use it to destroy the universe and its many worlds — including Mid-World, teased in the above photo. Matthew McConaughey plays The Man in Black in the upcoming adaptation, which also stars Abbey Lee, Jackie Earle Haley, Vikings’ Katheryn Winnick, Fran Kranz and Michael Barbieri.

The film hits theaters on February 17, 2017.
