This movie was better than Steve's McQueens Blob movie which was okay, but i thought Caltiki's story was more interesting and the effects was very good for the period of time that it came out. The effects was a okay in my book and when i saw it as a kid in the early 1960's, it scared the day lights out of me! I think it is one of the best movies of blob like movies that i ever did see. There's a lot of good movies within the past 60 some odd years that had blob like creatures or single cell protoplasm creatures in them. This i feel is one of the BEST films i ever did see. None hold barred! Caltiki the Immortal Monster is the best movie i ever saw and i highly recommend it to anyone!
