Governor Negan Edition
Comic book Negan is based on Henry Rollins He auditioned for the television series, but of course the role went to Jeffery Dead Morgan.
For Season 4, David Morrissey lost weight to show the hardship the Governor faced. While the weight loss was real, the hair and beard were fake, specially made for him in London.
Negan was a teacher and ping pong coach pre-apocalypse.
The Governor uses the name Brian as an alias, this is a reference to the novel "The rise of the Governor" by Jay Bonansinga, in which Brian is his real name and Phillip is the name of his dead brother.
Negan was listed on the casting call as Orin. It is a common The Walking Dead tactic to call characters being casted alias and having the potential actors read from scripts that have nothing to do with the actual series.
