Gammon delivered the voices of cartoon characters Marv Loach and Floyd Turbeaux in warner Bros. Feature film The Iron Giant of 1999.  ”I would like to take a moment to speak directly to you, Dr. Freeman. Yes, I speak to them, what is called the ”One Free Man”. I have a question for you: how could you throw it all away? He`s a ghost. A man of science with the ability to waver reactionary and anxious minds towards the truth, choosing instead to take a path of ignorance and decadence. Don`t make a mistake, Doctor Freeman – it`s not a scientific revolution you`ve unleashed, it`s death and the end! You have brought down humanity into free fall. Even if you had offered your capitulation now, I cannot guarantee that our benefactors would accept it. For now, I fear that they have begun to look at me with suspicion, to the point that they serve as representatives of humanity. Help me regain your trust, Dr.
Freeman. Pass while you still can. Help us to ensure that humanity`s trust in you is not diverted. Do the right thing, Dr. Freeman. Serving people. Gammon is perhaps the best for his characters, Lou Brown, manager of the Cleveland Indians in the major leagues, and Nick Bridges, the father of Don Johnson`s main character in the television series Nash Bridges. He starred in the films Cool Hand Luke (1967), Urban Cowboy (1980), Any Which Way You Can (1980), Silverado (1985), Noon Wine (1985), The Milagro Beanfield War (1988), Major League (1989), Revenge (1990) The Adventures by Huck Finn (1993), Major League II (1994), Wyatt Earp (1994), Wild Bill (1995), Truman (1995), The Hi-Lo Country (1998), Cold Mountain (2003) and more recently Appaloosa (2008). He also had an unrecognized role in Natural Born Killers (1994). During HalfTime 2, Dr. Breen is often seen and heard doing ”Breencasts” – urban propaganda video programs with which he speaks directly to citizens and lots of powers. Breencasts consists of everything from the doctor who deals with citizens` concerns to an outlet for pro-combine propaganda. In both cases, Breen calls the ”universal union” or ”Our Benefactors,” which never use the term ”combine,” except to try to mock the term.
But when he is relaxed and not in front of the audience, he himself seems to use the word ”combine.” Wallace Breen was at the time of the Black Mesa Incident in 200. During the events featured in Half-Life, it is neither seen nor mentioned directly, but always called ”administrator.”
