I speak of personal medallions often. I first heard this line in Francois Truffaut's 1966 movie Fahrenheit 451, starring Julie Christie, Oscar Werner, and Cyril Cusack. I have never forgotten the personal medallion reference. Unable to find a film clip of the conversations involving personal medallions, here is the dialog is from the script. The Captain, played by Cyril Cusack, is speaking to a junior fireman, Montag, played by Oscar Werner, who is about to get a promotion. I found this an important point in the film, because towards the end, a nearly identical dialog takes place, in which Montag answers honestly but not in his best interests. The Captain: Have you seen my personal medallion? It's a remarkable likeness. You must remind me to let you have one sometime. Towards the end of the film, the dialog changes slightly. The Captain: Yes, you're a good man. Remind me to give you one of my personal medallions. The likeness is remarkable. You'll see. Montag: I, uh... The Captain: You, uh... Montag: I already have one, sir. I'm fascinated by the notion of what we have in the past and currently use as our "coat of arms", emblem or otherwise that which identifies us.
