Movie fans in the United States are expected to flock to their neighborhood theaters Friday, to see the fourth installment of the Rambo series, which portrays Burmese government forces as the main villain.

The series, starring veteran actor Sylvester Stallone, revolves around a U.S. veteran of the Vietnam War who engages in extreme acts of violence against an equally brutal enemy.

This latest installment finds Rambo living in exile in Thailand when he is recruited to take a group of American missionaries seeking to help a group of ethnic Burmese villages caught in the middle of a civil war. He later joins a team of mercenaries to return to the village after the people there are attacked and slaughtered by Burmese government forces.
