Below is a kind of brief "Intro to The Dark Tower" video that covers the basics about the characters of Roland Deschain (the Gunslinger), the Man in Black, and the Dark Tower itself with the actors and Stephen King briefly talking about them.
Below are three new (and first) TV spots for The Dark Tower that begin to show off the movie. Many of the scenes are recycled from the trailer but there is some new stuff. Movie hits theaters on August 4.
