This actually played for a while about 2 years ago at a theatre here in Tokyo. The English title was CREATURES FROM THE ABYSS and the Japanese title translated as OBJECT X. It was an English language print and watching this late 70's/ early 80's-look trash in a theatre was a nice experience that made me wish I could have experienced 42nd st. in it's heyday. At the time I thought it was a new release and that it copied the British PROTEUS. But if it was made in '94, I guess the opposite is true.
