Immortan = Homem Imortal
De uma entrevista com Hugh Keays-Byrne , o ator que interpreta o Immortan Joe:
Q: What is an “Immortan?”
KEAYS-BYRNE: “Immortal Man.” So the cult, the idea: you can’t kill me. I’m here forever, and I just keep going in this mayhem that we are surrounded with. This natural world which is falling apart, I am able to control. Out of the ashes you will rise, with my help.
