Here's the blurb from a 1970 film, with some names changed, which follows up the earlier story of an evil super villain who tried to conquer the world but was defeated by a suitable hero overcoming all odds. As he does again in the sequel (oops, spoiler alert).
"Evil Super Villain returns from exile and once again seizes control of his former minions in a bid to reclaim his empire, and the Super Hero leads the opposing allied forces in the fateful battle to come. Drama, starring Rod Steiger, Christopher Plummer, Orson Welles and Virginia McKenna."
Of course it's Waterloo (the Napoleon and Wellington version, not Abba's), and the real question is why real life is so clichéd that history reads like a screenplay that would be too mindless to ever get proper actors if it wasn't true. No wonder emperors were numbered like film franchises.
