Michael Rooker has been cast in the Amazon Studios adaptation of Stephen King’s The Dark Tower, currently filming the pilot episode on location in Croatia.

Rooker’s role in the series pilot is still being kept under wraps, but there is no lack of information and speculation around the much-anticipated series. Variety previously reported that Sam Strike will play Roland Deschain, aka The Gunslinger, while Jasper Pääkkönen is believed to be playing The Man in Black, also known as Randall Flagg.

The series will consist of a total of 13 episodes, developed by Glen Mazzara (The Walking Dead), Akiva Goldsman (Titans, Star Trek: Discovery) and writer Stephen King. The Dark Tower will tell the story of how Roland became a gunslinger and his first encounter with the villainous Man in Black. The Dark Tower is scheduled for release in 2020.
