With Amazon Prime currently assembling the cast for their upcoming small-screen take on Stephen King’s The Dark Tower, now comes word that Jerome Flynn has joined the series.

Courtesy of Birth.Movies.Death, the Game of Thrones actor has signed on to join Sam Strike and Jasper Pääkkönen in the show. The current speculation is that Flynn may be playing Eldred Jonas, the leader of the Big Coffin Hunters group who have ties to Roland Deschain.

For the series, Strike is playing Roland Deschain/The Gunslinger, while Pääkkönen is playing Randall Flagg/The Man in Black. In the movie take on The Dark Tower, those roles were played by Matthew McConaughey and Idris Elba, respectively, of course.

Originally, this Dark Tower TV show was to be tied to the aforementioned film. That was until, frankly, the feature disappointed on plentiful levels. As such, Amazon decided to change gears and instead make this TV offering a more faithful adaptation of King’s famed books.

The Walking Dead and Damien’s Glen Mazzara is acting as showrunner and executive producer on the series.
