Production on "Rambo IV" is finally expected to commence October 1st in Thailand and talking with Entertainment Weekly, Sylvester Stallone says a lot of the delays in the last two years which stalled the film revolved around the lack of a potential enemy.
After ruling out the Mideast, Africa, and Korea, the actor finally hit on a solution "I called Soldier of Fortune magazine and said, 'What is the most critical man-doing-inhumanity-to-man situation right now in the world? Where is it?" says Stallone. They came back with Burma (aka. Myanmar), the largest country geographically in mainland Southeast Asia.
Art Monterastelli ("The Hunted") co-wrote the script with Stallone which finds Rambo living a monastic lifestyle in Bangkok and salvaging old PT boats and tanks for scrap metal. When a group of volunteers bringing supplies into Burma disappears, a relative of one of the missing missionaries begs Rambo to find them. He heads off with a team of young guns to find them.
