Syd Midnight Based on a true story. Patton was really in love with his own image as the ultimate general, so it's hard to tell if he was just putting on a show to make his legend grow, or if he really believed he was the eternal warrior. Probably a little of both.
mouser Given he was partly responsible for delaying by as much as a year the advancement of british troops on Berlin (making them cannon fodder all that time) makes this very much plausible. He's an unfortunate hero. Born idiot.
theFlu I don't doubt he thought he was a reincarnated Roman soldier. Besides, having an ex-centurion who thinks it's possible to die and rise again, isn't exactly a bad thing in times of conflict.
Valkor A metaphor maybe? The eternal cycle of war? How his archetype is eternal?
IrishWhiskey Or just crossing that thin line between genius and insanity
Camonk My great grandfather apparently knew Patton, and upon seeing this movie he said, "Yeah, that was Patton--except for the voice. He had a high, squeaky voice."
