I'm a huge fan of Stephen King's 8 part Dark Tower series. It's a simple story of a man trying to make it to a mystical tower but in between he makes a few friends and a lot of enemies. Also he meets a suicidal train. It's Stephen King's self described magnum opus.
It was known before Matthew McConaughey would be playing the infamous man in black and now we know Idris Elba is playing the badass protagonist, Roland the Gunslinger. How many movies they're making or what parts of the book they'll be covering is anyone's guess. I just hope they don't screw it up.
"The man in black fled across the desert, and the gunslinger followed."
