RAMBO 5

Stallone teased us awhile back about one more Rambo but then the Expendables was picked up and he put Rambo to the pasture saying he was 99% sure Rambo was retired.    But according to this article at Dark Horizons there maybe something to that 1%: Dark Horizons

New "Conan the Barbarian" writer Sean Hood has reportedly submitted a screenplay for "Rambo: Last Stand" at Millennium Films reports Empire Online.
Hood says "I met with Mr Stallone twice last year. He gave me a book, an older screenplay, and about twenty pages he'd written himself to use as inspiration for the last chapter of the Rambo saga."
Reportedly this take isn't based on previously linked stories for another "Rambo" such as the sci-fi style "Savage Hunt", nor the Mexico-set cartel kidnap tale. Rather Hood says "It's more in line with the small-town thriller of First Blood."
However he stresses that a script does not a movie make - "I don't know whether Mr Stallone will actually do it. Right now, as I understand it, he has his hands full with Bullet to the Head and Expendables 2. But Millennium films did hire me to complete the screenplay and realise his story, and my hope is that he'll eventually be inspired to do one more Rambo film, with the tone of Clint Eastwood's 'Unforgiven'."

There are thousands of screenplays out there that never get made but if Hood actually met with Stallone and Sly himself gave the guy a story to go off of that would certainly indicate a level of interest on Sly's part.  I would like to see one more chapter of Rambo especially if it is more like the first one with a little Unforgivn  mixed in.  A fitting way for Sly to bow out of action movies and turn his attention to directing more.  At the end of First Blood Rambo says, "Nothing is over! Nothing!  You just don't turn it off!"  Hopefully for Rambo fans that is the case here.

"The screenplay needs more killing I said!"
