No joke! There is another Rambo movie on the horizon. And it is called Rambo: Last Blood. That is of course a play on the original 1982 film First Blood.
Stallone co-wrote the story, which is said to be the final film in the series. Adrian Grunberg, whose only other directing credit is 2012’s Get The Gringo, will be helming the film. It will be released in September, and will likely carry the franchise’s usual “Hard R” rating.
