...so apparently John Wayne was offered the role of Marshal Dillon. He said he didn't want to do a "television Western." So he instead suggested a guy by the name of James Arness, who made the character his own.
So...what if John Wayne had taken the offer?
(by the way, I just wanted to say that John Wayne and James Arness both made the right choice. James Arness was an amazing actor, both physically and mentally.)
