The end of the last Rambo movie left things wide open for a potential sequel to this long running series. Stallone's got some more miles in him than many thought. When Rambo ends the last film, he's killed off what seems to be half of the population of Burma and rescued the damsel in distress. He takes her advice and decides to return back to his home in Arizona, apparently to see his father.

It's not likely that the next Rambo film will be a heart warming exploration of a father son relationship. If it was something more like Tuesdays with Morrie than First Blood, it would be the most surprising turnaround in Hollywood history. While Stallone has gone on the record saying that there will be another Rambo film, the details have been tight. He's said that he's still writing the script, and that it won't be a war movie. This doesn't make too much sense, as Rambo is all about war films - could Rambo be taking up kick-boxing or something? Who knows.

He's intending to shoot the next film in Bulgaria, but there's no telling what that indicates. All that's really known is that it's going to be set in Arizona. The previous film did reasonably well worldwide, earning $105.8 million relative to its budget of $44 million. Stallone will presumably reprise his role as Rambo, and perhaps get in some character development to one paradoxically known for its complete lack of depth and focus on mindless action.
