Sylvester Stallone has threatened to expose Burma's killing fields if country officials ban his new movie RAMBO there. The action man shot the movie in the jungles of Myanmar - formerly Burma - and is upset the violent film might not reach fans following an official crackdown on the distribution of pirated copies of Rambo. The Burmese authorities are said to be upset with the plot of the film, in which Stallone's character tackles the country's military in a mission to free a group of captured Christian aid workers. The angry actor/director fumes, "If the Burmese government has nothing to hide, I am wiling to go there and show the world where thousands of bodies of innocent women and children are buried. "Let the generals look me in the eye and tell me they have a free country. It will never happen."
