Next year, the Dark Tower movie is going to hit theaters—but a year later, it’ll have its very own companion TV show hitting the airwaves, featuring at least one of the the film’s major stars. And now we finally have some details—including the fact that the movie’s star Idris Elba will appear on the show as well.

The makers of The Dark Tower film are unwrapping their plans for the saga’s companion TV series.

The movie — starring Idris Elba as the gunslinger Roland Deschain, and Matthew McConaughey as the menacing Man in Black — opens on Feb. 17 and explores the hero and villain’s opposing quests to reach an otherworldly tower that connects their apocalyptic realm with ours.

Ever since the film project was first proposed, it came packaged with an unusual idea: a spin-off TV show that would fill in the fantasy epic’s prodigious backstory.
