Yes, the black and white clip of the guy in jail is Doug (in the beginning). I just watched and the other black and white clips are of an unknown character (go to the Crystal Ball if you want to know who the other young man in jail is). Funny that he was reading the story of Davy Crockett. Bill Hayes (Doug) had a hit song, The Ballad of Davy Crockett, in 1956. Here's the book the young man is reading, and the actual picture the prop department used of Bill Hayes dressed as Davy Crockett from back in the day.
