Well, it has been confirmed. Graham McTavish is Saint of Killers in Preacher and we get to see him in episode #2. We have to give Bleeding Cool credit on this one. All we can say is:
From what we understand, the second episode starts with a scene set in 1881 and a mysterious character, wearing a cowboy hat, is striding away from his wife and a sick child in search of medicine. Those of us that have read the comic books know that Saint of Killers is a man who loves to stride in and out of a scene.
We cannot wait to see the reaction when Saint of Killers shows up at the beginning of the second episode. Fans are going to shit a brick. Hell, he is top 10 villains in comic book history. Some have even ranked him in the top 50 characters in comic books.
