Back Door to Hell
Back Door to Hell is a 1964 film concerning a threeman team of United States soldiers preparing the way for Gen. MacArthurs World War II return to the Philippines by destroying a Japanese communications center. It was produced on a relatively small budget and received lukewarm reviews, and is most notable as one of Jack Nicholsons earlier roles. Hellman, Nicholson and Hackett also made the film back to back with Flight to Fury 1964.
The film, directed by Monte Hellman, was shot on location in the Philippines, giving it a particularly authentic look. The same plot was reused in Ib Melchiors Ambush Bay 1966 with a larger Marine patrol destroying a minefield prior to the American and Filipino invasion of the Philippines.
