Big deal, one would think. He's always does this kind of stuff. Except, this movie is Malay/Indonesian! About a legendary Malay/Indonesian ghost thing!

PenanggalanCountry: Malaysia / Indonesia
Directed by Tulsi Ramsay
SUMMARY: (from IMDb): Tara (Tanny) is a village girl with extrodinary powers, capable of harvesting both black and white magick elements. However, this girl holds a dark secret that her mother and father (both are magick researchers) have been keeping from her. Tara's sister, Durgha (Suzanna), is a Penanggalan, an undead being that could remove it's head at will to swallow the living whole and has bloodthirty qualities, later turning Tara into a Penanggalan. When Tara finds this out, her family, her boyfriend Rocky and even Tara herself must watch over Durgha and monitor what she does. When the town finds out about Durgha and talks about slaying her, Durgha promises Tara to hand down her powers, so she could break Tara's Penanggalan curse and live a normal life, still having control of her extrodinary abillities.
