Everybody in Hollywood knows that sequels are hot. People love to watch the movies they love but later in time and with larger budgets. Almost as popular: Prequels. Sometime after the release of "The Phantom Menace" it seemed like prequels were the next big thing. "Batman Begins," "Casino Royale," "Hannibal Rising," and other movies ran with the idea of seeing our favorite characters from before they were famous. But some movies escaped the prequel-maker's iron. Here are five prequels that should be made before the audience withers away and dies.

"Unforgiven: Forgiven"

Clint Eastwood begins "Unforgiven" as an aged badass gunfighter with a reputation as fearsome as his low growl. The glimpses into his deadly past are pretty chilling, but they also provide fertile ground for a prequel. We could see a young William Munny getting into all kinds of adventures, and killing all kinds of innocent women and children! This could be fun for the whole family.

"Apollos 1-12" 

Ron Howard's smash hit "Apollo 13" shows the failed 13th Apollo mission to get a man on the moon. But what about the the 12 Apollo missions that came first? Where was Clint Howard during those? Some of those missions weren't even manned, so we as viewers could be privy to the drama of a completely unmanned spacecraft hurtling through space - will it get back? Think of the costs involved! It's practically a license to print money.

"Pac-Man Begins"

The video game "Pac-Man" has enthralled everybody from college students to grandmas, and the reason is simple: The sense of mystery that accompanies each game. Who is Pac-Man? Why is he so hungry? What are those ghosts the ghosts OF, exactly? A prequel could answer all these questions and more. Although it might be kind of sad to watch Blinky, Pinky, Inky and Clyde get picked off one by one.

"Seinfeld: The High School Years"

Cool thing about this concept is that if the movie is a hit, you have definite potential as a series. Basically, it follows Jerry, George, Elaine, and Kramer as they struggle to fit in, get to class on time, find dates to prom, etc. You'd have some pretty glaring continuity issues to deal with, like the fact that Kramer is supposed to be around 10 years older than the other characters, but who's really going to care about that after watching a teenaged George have to climb the rope in gym? This comedy writes itself!

"Drive: Indiana"

We never find out exactly where Ryan Gosling's Driver in "Drive" is originally from, so why not the midwest? We could watch him get involved with the Indiana corn mafia, driving a getaway tractor for heists, and eventually being forced to flee to LA. If you thought Gosling looked good with a hammer, you should see him with a corncob. Intimidating!
