Snake People

This Mexican horror outing follows the attempt of a police inspector to find a wealthy man's niece who turns out to have been abducted by crazed worshippers of a demon serpent. The film is most notable for being one of Boris Karloff's last films. Because he was terribly ill at the time, his scenes were shot in Los Angeles and edited in later. He made three other Mexican films in this way. The film is also known as Cult of the Dead and Isle of the Snake People.
