With Expendables 2 in the rearview mirror, Sylvester Stallone is looking to his next project, this one involving creatures!
Stallone has owned the film rights to the novel Hunter by James Byron Huggins for about 10 years now and never managed to make a film adaption.
According to Yahoo!, Stallone and Lionsgate have inked up a deal to fast track Hunter for 2014 release date. Stallone is set to star, write and direct, which will be filmed in 3-D.
In the book, 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 is a job Hunter cannot turn down, but he soon discovers that his prey is terror incarnate, a half-human abomination created by a renegade agency through a series of outlawed genetic experiments. It has mans cunning, a predators savageness, and a prehistoric power that has transcended the ages. And even if Hunter survives its unrelenting hunger for human blood, hell still have to confront the grim reality that it may have grown immortal.
