Here is a video of Sylvester Stallone training for Rambo: Last Blood.
The film will see old John J. take on Cartel rapist sex traffickers, presumably with extreme prejudice. Hopefully the methods used would probably make Brian Mills try to run in and plea for clemency.
The movie will shoot across Bulgaria and Spain.
The film was briefly green lit and was in development using the story line of The Savage Hunt, an unrelated sci fi novel that Stallone owns the rights of. It would have seen Rambo tracking down a genetically engineered beast that had broken out of a laboratory. After an outcry from fans Stallone nixed this angle and a new storyline focusing on a Mexican slavery angle was proposed, Mickey Rourke was approached for the role of the villain.
