Wow with posters like that... who wouldn't want to watch this movie?
I have the VHS... but... it's terrible movie. When it ended I didn't know what to think of it. Like "what the heck did I just see?" BUT... there are troopers and horses and a scout car and a sherman tank ( a pretend Japanese tank with no infantry support all by it's lonesome) in the movie. And there's Ursula Andres.
This movie was shot partly in my town Pagsanjan and the adjacent town Lumban in Laguna the first man-made lake Caliraya is. Ursula stayed in two local resorts and people were tickled to the max because she would be lounging and swimming in her bikini. In those old days, that was almost scandalous! Parts of the movie were also shot in Baguio.
