Last week, Entertainment Weekly revealed a slew of new photos and details for the long-awaited adaptation of Stephen King's The Dark Tower books. With production still under way, it isn't clear when we'll get to see the first footage from this movie, but today we have word that the EW cover contains a hidden message. The number 19 has a special significance to readers of the book, so it shouldn't be too surprising that this reveal comes today, on July 19.

Entertainment Weekly reveals that there is a new app fans can download for either Apple or Android devices called The Sombra Group, which the site reveals will "come in handy" as we get closer to this adaptation's February 17, 2017 release date. After downloading the app, fans can turn this app on over a copy of Entertainment Weekly's Dark Tower cover, featuring Idris Elba and Matthew McConaughey, for a special surprise. You can take a look at a photo we took of the EW cover below, with the Sombra app revealing the hidden message.

In the Dark Tower books by Stephen King, the Sombra company is the legitimate business front in our world for the followers of The Crimson King, a god-like being who, with the help of The Man in Black (Matthew McConaughey), wants to destroy The Dark Tower. The corporation opens portals between other dimensions while allowing mere mortals to see things that would normally be hidden from the rest of humanity. We'll have to wait and see what other hidden images will be uncovered through this new Sombra group app as production continues on this adaptation.

Last week's EW coverage also confirmed a rumor that had recently surfaced, that claimed The Dark Tower is actually a sequel to the original books. The speculation began when set photos revealed that Roland has come into possession of the Horn of Eld. Stephen King's final novel ends as the first novel began, with Roland Deschain (Idris Elba) chasing the Man in Black (Matthew McConaughey), but this time, he holds the Horn of Eld, which was long thought to be missing. Director Nikolaj Arcel confirmed that this movie is in fact a "secret sequel" to the books.

The supporting cast includes Abbey Lee, Katheryn Winnick and Michael Barbieri, with Nikolaj Arcel directing from an adapted screenplay by Akiva Goldsman and Jeff Pinkner. Sony Pictures will release The Dark Tower in theaters on February 17, 2017, going up against Warner Bros.' Fist Fight, Universal's The Great Wall and 20th Century Fox's A Cure For Wellness. Take a look at these photos taken with the Sombra Group app, and stay tuned for more updates on The Dark Tower.
