Jaani Dushman (1979)
Jaani Dushman features a crazy big cast of Bollywood stars, the music is mostly great, the locations are lavish, and the horror is completely wild. And there's a man wearing a silly monster suit and fangs strangling ladies to death. What more could you want?

Disco Dancer is the most entertaining Bollywood film I've ever seen. It has everything you could ever want in a film: disco dancing, death by electric guitar, incestuous undertones, and fights. The fight in the clip below is a definite highlight.
Junoon (1992)
Junoon's illegitimate inspiration comes from a classic of the horror genre, An American Werewolf in London, and it has just right amount of ludicrous originality to place it among the best Bollywood horror films around.
