I found more recent information about the John Wayne in Color set.
The three included films have state of the art colorization by Legend Films. Also included are the black and white originals, a policy Legend adheres to for all its product.
Visit Legend Films to see samples of their work and much interesting reading about their digital process. The films are done to such a high resolution that they can strike 35mm prints.
And let's not forget that Legend Films has three more wonderful colorized films from his Lone Star days coming out this Tuesday. The first box set of films looked great...can't wait to see these next three!
