Sally Yeh's forgotten cannibal movie

I watched Cheuk Ang-Tong's MARIANNA tonight. It's a HK horror movie from 1982 mostly shot in the Philippines. One of the two female leads is played by Sally Yeh (whose most famous role is probably John Woo's THE KILLER). Yeh's character's husband goes to the Philippines on a business journy and "bumps" into a Filipino girl who's seemingly wanted by everyone; two tribes of blood thirsty savages and a horde of cannibal zombies are out to get her. There's tons of cool stuff and heaps of gore. I was highly entertained. The film is only released on a very rare HK VCD. The dialogue is a mix of Cantonese, Tagalog, and English (Mandarin is optional instead of Canto). The VCD has Chinese and English subs. Watch it if you can find it! Oh, the ending is terrible by the way, haha
