A US soldier deserts the army while serving in the South Pacific during World War 2. Starving to death in the jungle, he makes a deal with Satan in order to save his own life. In return, he becomes a servant of the devil, occupying the bodies of various recently deceased men to bring out the latent evil in those around him. Another part of the curse is that he occasionally change into a ravenous, murderous beast and goes on a rampage.
The main problem with Beast of the Yellow Night is the convoluted plot which is as confusing as the title (since when are nights yellow?). There are certainly some great ideas here and the writing is half-bad, but unfortunately those interesting concepts are never fully explored. It wants to be a deeper and more philosophical film than it actually is. Apparently Eddie Romero is quite a highly-respected director in the Philippines. American producers used to commision quite a few B-movies from that country during the 70s, interestingly enough, and this is just one example.
An interesting piece of trivis is that, early in his career, lead actor John Ashley auditioned for the starring role in "I Was A Teenage Werewolf". He was unsuccessful, but here with his regular partner Eddie Romero he finally got his chance to play a werewolf-like creature, in what he describes as the most cerebal film he made during his time in the Philippines. Later he became a successful television producer, working on such shows as The A Team (which he also narrated).
This is an interesting movie, if not a particularly good one overall. However, if you're a fan of B-movies of this era you will probably find something to enjoy here.
It is debatable whether or not there is actually a werewolf movie. From appearance alone, the "beast" could just as well be a generic demon. However, given the wolf-like nature of some of the beast's attacks, and some of the transformation sequences, I think this qualifies overall as a werewolf movie. Or at least an interesting footnote to werewolf movies.
The quality of the makeup is about average for B-movies of this particular era - in other words, not great. Some of the gore effects are quite good, though.
