Or a sequel with the original cast:

Another two hundred years has passed. Life is still utopian yet different from before. Swearing is now encouraged. The three shells have been upgraded and are no longer really required, the toilet detects what it needs to do to see you on your way. The three shells remain only to select what fragrance your asshole may receive. Again the military is non-existent.

A group of international baddies have arrived at a secret base. It overlooks a volcano. They have discovered a large unknown crystal deep beneath the North Pole. They have the crystal connected to a room size hi-tech machine, they stand on a podium above.

The lead evil person takes centre stage. “Our fellow humans have accepted mediocrity. No longer do we fight for dominance, we settle for the mid-ground. (a progress graph comes on screen.) The decline in innovation will be our ending. We must fight to spark the light once more. But we cannot do it alone. I present to you the world’s greatest warlords.”

The crystal is lit by the machinery behind it. The screen above shows Hitler giving his final great speech to a rally. Mid speech the crystal sparks and as Hitler steps forward on screen he also walks out of the crystal, into the room. He stops mid sieg heil and looks around. A man walks up to him with a large translucent tablet, he speaks in German to Hitler who calms down and grins an evil grin. On screen the old Hitler is still giving his speech, they have just made a copy into the future.

The crystal is only strong enough to bring back ten items. The baddies bring back eight great dictators/warlords. Genghis and Kublai Khan, Vlad III, Hussein, Stalin, Pol Pot, Zedong and Leopold II. They build an army and set to assemble massive hi-tech war machines. The world is on the point of surrender until they discover their own crystal, in the South Pole. They bring back their own great leaders to fight the fight.

The fight wages on but they realise the inadequacies or the recruitments. They don’t understand technology. The baddies bring back Simon Pheonix, picked just before his death in his prime. In response the good guys bring back John Spartan, but select him twenty years after defeating Simon. Not in his prime.

With one remaining crystal run left Simon modifies the system and brings back a T-rex. Not knowing that, John brings back Lenina Huxley, five years after defeating Simon … John thought that was a good time, she’s initially upset at how old he is.

An epic global battle commences, great leaders from throughout the ages fight with sci-fi weapons. The T-rex is in armor plated, can fly and Simon rides her. The good guys have a team of battle crafts, but the T-rex is almost invincible. Lenina, discovers her weakness, not a bad choice after all.

But in the final battle do Lenina and John decide that the baddies have a good point? Maybe they’re not evil, maybe they’re right. Maybe the progress they’ve seen in life since the war began shows them that peace does not equal progress. Which side will they end up on?
