Trivia, insights & behind the scenes
Director Ferdinando Baldi made Django (1966) and Comin' at Ya! (1981), bringing his signature spaghetti western chaos to Vietnam. The bus was reportedly a real decommissioned school bus that broke down constantly.
Shot during the Philippines' exploitation film boom, where cheap labor and locations attracted B-movie producers worldwide. Filipino stuntmen performed death-defying work for pennies compared to Hollywood standards.
