Not a great film, not even great by exploitation standards but is a colourful and entertaining enough watch. The two leading ladies fleeing jail chained together in flimsy little costumes and traversing the Philippines landscape while two major gangs of men search them down, is bound to have some interest. The influence of the film with regard to the development of exploitation cinema including blaxploitation is undeniable. Director Eddie Romero was born in the Philippines and had worked there for many years making popular cinema, particularly war films, with the emphasis on the Japanese invasion, and later some horror with as much skin as was allowed. When Roger Corman and Co came calling he was ready to assist and not only were WIP films about to get a boost but Jonathan Demme and Pam Grier would be introduced to the world. Demme, credited with script assistance here, actually ripped off the earlier Kramer film, The Defiant Ones but crucially switched the two chained guys, Tony Curtis and Sidney Poitier for Pam Grier and Margaret Markov. Pam Grier, of course, proved unstoppable and whilst her co-star here did a few more films before leaving cinema behind, she became the Queen of Blaxploitation and more. mention should also be made of that big, bad, bearded man Sid Haig, who romps through the film in a cowboy hat, taking anyone or anything as it comes and is still working today.
