Frank Darabont declarou que DeMunn saiu devido a ações de executivos da AMC
No final de 2013, a IGN entrevistou Darabont sobre as circunstâncias por trás das cenas de The Walking Dead que levaram à partida de Darabont e à saída de membros do elenco incluindo Jeffrey DeMunn:
Were they [the AMC executives] simply not willing to provide the budget you needed in order to do what you needed to do?
DARABONT: The big crux of our argument was budget. If somebody comes and hands you the biggest hit you've ever had you don't just say, 'Okay, now we're going to cut your budgets by 25% across the board. And we don't give a s--t if you care, if you don't like it.' That's just...I don't even understand that kind of thinking. Or how much punishment it visits upon the people who are actually making the show, which was incredibly difficult to begin with. Cutting your resources by a quarter in the following season so they work even longer hours and under harder circumstances? It's inhuman. I'll write a book about this one day.
Did you ever have a debrief with the cast and crew? At the time, it seemed like everyone was really afraid to comment.
DARABONT: Oh yes, they were bullied, and threatened, and their livelihoods threatened, and there was some weight being thrown around. Like I said, I'll write a book. And there are a lot of people who will go on record. That are actually very keen to go on record, because like I said there are a lot of people who felt tremendously abused.
What were the conversations like? Jeffery DeMunn did end up leaving the show.
DARABONT: Yeah, Jeff didn't want to stick around. Because Jeff is a human being and he's got a tremendous...he doesn't need the work. He doesn't have a very extravagant lifestyle and he wants peace of mind in his life. He's a very good and decent man that way...

Portanto, parece que, pelo menos segundo Darabont, DeMunn partiu porque estava sendo exposto a um ambiente de trabalho hostil / injusto e não precisava do trabalho o bastante para aguentar isso.
