Rambo's impact is full on real.

"The Burmese military junta has ordered DVD vendors in Burma (otherwise known as Myanmar) not to distribute the film due to the movie's content.^[21] Rambo is available on bootlegs however, and it is a great hit amongst the Karen Freedom Fighters and Burmese exiles critical of the Burmese military dictatorship. According to Karen Freedom Fighters, this movie gave them a great boost of morale. Burmese Freedom Fighters have even adopted dialogue from the movie (most notably "Live for nothing, or die for something") as rallying points and battle cries. "That, to me," said Sylvester Stallone, "is one of the proudest moments I've ever had in film."^[22] Also, overseas Burmese praise the movie for its vivid portrayal of the Burmese military's oppression of the Karen people.^[23]"

"Actor Maung Maung Khin, who played the cruel Burmese dictator Tint, fought for the Karen Rebels in real life, and was afraid of his family getting murdered by the enemy if he took this role. He went ahead and took the role anyway."

What effect does Stallone anticipate this image will have on Japanese viewers?

"You know, it's a two-edged sword," he said. "I was hoping that they understand that this is not a Sylvester Stallone self-indulgent action film. That actual, real people that are contributing to hopefully the betterment (of the situation) and reporting the truth, pay with their life. So, I'm just trying to take that harsh brutality and segue into a film, and it's a very delicate line.

"But the most important thing was to establish that Burma exists. People don't know about it in our country (the United States). They think it's like: `Burma? Sounds kinda quaint, kinda cute."And I wanted to show that, `No. Here's actual footage, these are people dying ..." And you should have seen what I left out. It was even worse. Much worse. And I know that people couldn't take it.

"Here's the problem with doing a film," he continued. "You want the truth. You want cinema to reflect and dissect reality, but a lot of us aren't equipped to accept it. We live in a society where we've been sheltered a little bit ... That was a hard thing to push."
