Blood Thirst (also known as Blood Seekers and The Horror from Beyond) is a 1971 American black-and-white horror film produced and directed by Newt Arnold, and starring Robert Winston, and Yvonne Nielson. Shot on location in the Philippines in 1965, the film tells the story of an American detective investigating a series of murders linked to a Manila nightclub. The killings are carried out by a monster so that a beautiful blonde woman, who is actually hundreds of years old, can use the victim's blood to stay forever young.
