Project Terror: Blood Creature (1959)

Terror Is a Man (also known as Blood Creature, Creature from Blood Island, The Gory Creatures, Island of Terror and Gore Creature) is a 1959 black-and-white Filipino/American horror film directed by Gerardo de Leon.
It was the first in a series produced by Eddie Romero and Kane W. Lynn known as the Blood Island series, which also included The Brides of Blood Island (1966), The Mad Doctor of Blood Island (1969) and Beast of Blood (1970). All four films took place on an island called Blood Island, named for its vivid red-hued sunsets. The film focuses on a shipwreck survivor washed ashore on a small island where a scientist is experimenting on a panther in an effort to make it human.
Terror is a Man was partially based on H.G. Wells' novel The Island of Doctor Moreau, although Wells is uncredited in the film.
Terror is a Man was theatrically released in the United States on December 12, 1959 on a double feature with another Eddie Romero film, The Scavengers. The film was subsequently re-released under several alternate titles over the years, including Creature from Blood Island, Gore Creature, The Gory Creatures, and Island of Terror. It was re-released to theaters in 1969 by distributor Sam Sherman as Blood Creature. A warning bell gimmick sounding like a telephone ringer warned the audience of impending gore during a surgical sequence.
