It looks like Rambo will return - though not in the form you might expect.
According to Ain't It Cool, Sly Stallone has been talking to Swedish paper Metro, stating: "I would like to take Rambo to another genre, experiment a little with the character. It would definitely not be another war movie. I can't go any further with that than what I've already done. What it's going to be like, I'm not going to reveal at this point. But I'm already halfway though writing the manuscript."
For AIC's guesses as to what that genre could be, head over to the site. Ideally, we'd like to see a Rambo Vs Batman Vs The Terminator Vs Robocop flick, but that's probably not the direction Stallone's headed to, creatively.
