Sylvester Stallone is on board for John Rambo as an executive producer.
The 79-year-old action movie has served as a writer on the first five Rambo films and even directed 2008's Rambo, and while he won't appear on screen in the upcoming prequel - which is set before 1982's First Blood - he will still be heavily involved as Noah Centineo takes on the iconic role with Jalmari Helander directing.
