Devil Fighter – 1969 – is a Taiwanese fantasy film directed by Poon Lui and starring Pa Gwoh (also in Island Warriors), Gam Sek (also in Monkey War), and Yee Hung
No known copy of this film exists in American collector’s circles, but as most of them aren’t living in Taiwan/China there could easily be copies there lying in basements or rental shops. The film has gained its notoriety thanks to the images showing characters fighting giant bat-things that look like some creatures from Latitude Zero.
