Blood Thirst (1971)

Directed by Newt Arnold
(actor & director credits courtesy IMDB.com)

When a murderous creature strikes in the Phillippines, leaving behind young female victims drained of blood, the local police are stymied, and call in a famed American detective for help.

This is a fun little chiller, which according to Wikipedia, was shot in 1965 but not released until years later.  It boasts excellent black and white photography and an interesting cast of characters, led by Winston's wisecracking detective.  Although obviously shot on a tight budget with nothing too elaborate as far as sets or locations, and the creature makeup being fairly limited, the film still entertains.  It almost plays like a James Bond movie, with Winston walking into dangerous traps, and romancing a woman who at first despises him.
