Sylvester Stallone recently revealed to Vulture that he is now in training for the upcoming fifth film in the Rambo franchise. Stallone said, “I’m starting to work out. I’m going to be appropriately vicious and all that stuff”, but went on to say that he plans on being a “killer with a heart” for the new feature film. In addition to this, Stallone says that he will portray Rambo as “smart, yet stupid. Tall, yet short. Broad, but thin” in a bid to cover “all the boundaries”. While this may not make much sense to us now, it hopefully will do when the film is released. According to IMDb, the film will feature Rambo facing off against a Mexican cartel. The film is also reported to be Rambo’s last adventure, so hopefully they make it a good one.
