Horror isn't a respected genre in the Philippines--actually, it gets little respect everywhere--but there's been good, maybe even great, work done in the country.
Gerardo de Leon started a trend with 'Terror is a Man' (1959), loosely based on H.G. Wells' 'The Island of Dr. Moreau,' but because of a small budget, Wells' monsters were reduced to one limping Leopard Man.
De Leon's atmospheric style made up for lack of monsters, however, and the film earned enough money that De Leon followed up with a series of so-called sequels, the 'Blood Island' movies: fun if carelessly made flicks full of nudity and gut-spattering gore.
De Leon also directed a pair of vampire films--'Kulay Dugo ang Gabi' (Blood is the Color of the Night, 1966), and 'Dugo ng Vampira' (Blood of the Vampires, 1971) which are worth seeing for the lovely visuals and seething subtext of incestuous passions.
