Beast of the Yellow Night

This 1971 film from the Philippines was written and directed by Eddie Romero who is considered a giant in the Filipino film industry. He has been honoured with numerous awards in his native country -- perhaps he has dropped this film off his resumé.
Romero is probably most famous to North American audiences as the directer of the 1973 exploitation flick Black Mama, White Mama (which was co-written by Jonathan Demme who would later direct Philadelphia and win an Oscar for directing The Silence of the Lambs. But I digress.)
In Beast of the Yellow Night, John Ashley plays a man who is saved by certain death by selling his soul to the devil -- now there's an original story! Not only has he sold his own soul, but he must also recruit new souls for the devil, turning into a hideous creature to stalk his victims by night. And that doesn't make a lot of sense; after all, if you're the devil trying to get people's souls, siccing a man-eating beast on them who eats them before they get a chance to scream out, "Satan, only you can save me!" doesn't seem to be efficient method of soul procurement. Then again not much in this movie does make sense. Thankfully, it's a mercifully short 87 minutes. And the make-up -- yikes!
Ashley, who passed away about 10 years ago, is probably most famous for being the narrator of The A-Team.
What I can't understand is what the reference to the "The Yellow Night" is in title. Maybe because it was filmed in The Philippines in a slightly less politically correct time?
