giant radioactive monster and while apparently prefer tokyo and do occasionally attack other major city and whether they be san francisco in it come from beneath the sea and or london and a in this movie . this one and call the behemoth and i think be refer to a a plesiosaur but look more apatosaurus like . the giant behemoth and aka behemoth the sea monster and be your average monster attack city movie . it spend an inordinate amount of time on people jabber along and scientist try to figure out what give dead people radiation burn and et cetera and et cetera . by the time i start nod off and the monster make his first appearance and and look kind of like a piñata . later it come on land and be a stop motion effect . this be willis obrien penultimate film . at this point and obrien and his technique have be surpass by those of his student and ray harryhausen . the behemoth look not much good than the dinosaur of the silent the lose world . still and i quite like it . there just something about stop motion effect that charm me . but these effect be too few and far between to make the movie worth anything .
