Oh, that Sylvester Stallone. Rambo V has just been greenlit, and rumors have been bouncing around like decapitated heads about the storyline. Originally, Sly was said to be "fighting his way through human traffickers and drug lords to rescue a young girl abducted near the U.S.-Mexico border," according to Variety just over a week ago. (Hence the aliens. Get it?)

Well, Sly Stallone decided to go straight to Harry Knowles at Ain't It Cool News with the straight story -- in fact, he left the Head Geek a freaking voicemail, which you can listen to here. (Can you imagine waking up to a VM from him? Just sayin'.) The plot of Rambo V: The Savage Hunt, as CS points out, is very similar to a book that Sly owns the rights to: Hunter by James Byron Huggins, which seems quite popular with the author's fans over at Amazon. ("BIGFOOT ON STEROIDS WITH AN ATTITUDE TO MATCH" trumpets one review headline.) You can peep a hard-to-read scan of the plot summary at AICN, or give your eyes a break and read the official write-up courtesy of ComingSoon after the jump.

John Rambo could track anyone - or anything - on earth. Now the military desperately needs him for a mission that his ultrasensitive instincts tell him he should refuse. A beast is loose somewhere north of the Arctic Circle. It has already decimated a secret research facility and annihilated a squad of elite military guards. And the raging creature is headed south toward civilization, ready to wreak bloody devastation.

It's a job that Rambo and his 22-year-old hunting partner, Beau Brady, can't turn down, but they and a team of highly-skilled special forces kill team discover that the prey is a terror beyond their wildest imagination - a half-human abomination created by a renegade agency through a series of outlawed genetic experiments. It has man's cunning, a predator's savageness, and a prehistoric power that has transcended the ages. And even if Rambo and Beau survive its unrelenting hunger for human blood, they'll still have to confront the grim reality that it may have grown immortal.

IMDB, which has been known to be wrong before, has Mickey Rourke listed as a rumored costar, as well.

So, what say you? Have you had your fill of Rambo? Will this crazy DNA-tweaked monster give the original Predator a run for its money? Is the human trafficking theme exploited by action stories?
