This segment Jack and Troy from ZiaComics.com discuss the casting of Idris Elba as the main character, Roland Deschain, in Stephen King’s Dark Tower movie.
In the story, Roland Deschain is the last living member of a knightly order known as gunslingers and the last of the line of “Arthur Eld”, his world’s analogue of King Arthur. Politically organized along the lines of a feudal society, it shares technological and social characteristics with the American Old West but is also magical. Many of the magical aspects have vanished from Mid-World, but traces remain as do relics from a technologically advanced society. Roland’s quest is to find the Dark Tower, a fabled building said to be the nexus of all universes. Roland’s world is said to have “moved on”, and it appears to be coming apart at the seams. Mighty nations have been torn apart by war, entire cities and regions vanish without a trace and time does not flow in an orderly fashion. Sometimes, even the sun rises in the north and sets in the east. As the series opens, Roland’s motives, goals and age are unclear, though later installments shed light on these mysteries.
