The Dark Tower type Movie

Roland Deschain’s ka-tet has begun to form, as Idris Elba’s gunslinger in the long-awaited Dark Tower movie has found his Jake Chambers.

Sources close to the production have confirmed to EW that newcomer Tom Taylor will play the key role of Jake Chambers, a young boy who Roland crosses paths with in the series’ first book on his hunt of the man in black. Taylor previously appeared in the BBC series Doctor Foster and also showed up in the now-cancelled TNT series, Legends, as the younger version of Sean Bean’s protagonist, Martin Odum.

Jake is one of the key players in Roland’s pursuit of the Dark Tower, a member of his ka-tet — a group gathered together by destiny. In the novels, Roland pulls the members of his ka-tet from various time periods in New York. His encounters and relationship with Jake, however, are much more complicated, as he first runs into the boy while chasing the man in black in his own world.

Tayor joins a cast that includes Elba as Roland and Matthew McConaughey as the man in black.

Directed by Nikolaj Arcel, The Dark Tower recently received a release date shift to Feb. 17, 2017. For more on the film, read EW’s interview with Stephen King and Arcel about the casting of the film’s two main roles and how this adaptation is bringing King’s sprawling series to theaters.
