Sly Stallone is set to play Rambo once again! Rambo John J Plot Outline: Vietnam vet John Rambo is forced to emerge from his reclusive lifestyle and take justice into his own hands after a girl goes missing. Blimey, Sly is going to be sixty.( Youâve got to have issues if youâre sixty year old Green Beret running around the woods with an M60 scaring National Guardsmen!) Strangely enough he actually avoided the draft during the Vietnam War by working as a PE instructor in a Swiss girls' school! I wish he would make a film about that!
