possible plot spoiler . hypnotist dr. lombardi ( chester morris ) put his assistant andrea ( marla english ) into a deep sleep . when this happen her thing in a past life ( the title creature ) come out of the sea and kill people . lombardi know this and predict the killing . dr. ted erickson ( lance fuller ) think lombardi be a fraud and try to prove it . he also fall in love with andrea which bother lombradi a lot . absolutely ridiculous story but this isn not a total bomb . some of the discussion on reincarnation and past life be interesting and there good direction and a really eerie music score . also the creature itself have become one of the legend of horror movie . it look pretty scary and have huge breast . you just have to laugh when the creature attack people and they just stand there and do nothing so it can kill them . the act waver . fuller seem to be ( wisely ) kid the material but isn not bad . morris be very serious ( and dull ) . english be just stunningly beautiful and very good in a tricky role . tom conway show up in a small role and have fun with the material . so this have it good point but the silly story and slow pace really wear you down . worth catch at least once for the monster . i give it a 3 .
