Is Sylvester Stallone done playing John Rambo? Based on a new rumor coming from Splendid Film, it sounds like he's not ready to put the Vietnam War veteran to bed just yet.

The website reports that a fifth Rambo movie is in the works, and is described as follows: "With Rambo V Sylvester Stallone returns in his iconic role. This time he goes up against a Mexican cartel. Stallone, who has also written the screenplay, describes the new Rambo as his version of No Country for Old Men."

Consider this one a rumor until official word comes down the line, but if a fifth film is as strong as the last Rambo, then we're all for round five.
