giant behemoth surprise me . catch the film really from the first frame for the first time in year i be shock by just how damn good the movie be . owe more to the british thriller such a the quatermass film and the stark black and white horror film of hammer ( x the unknown ) or thing like the day the earth catch fire ( which while release 2 year later have similar feel ) or corridor of blood and this be for a good chunk of the film a dark detective story of sort a the monster remain hidden and the scientist try to figure out whats go on . there be complexity of the story and fish kill and radiation and a sense that this be a large problem and that be lack from most american film of the time period and the genre . strangely and the monster and which always bother me and actually look pretty good . if you look at the monster itself i think you will see that compare to the beast from 20000 fathom and this be the good monster . if you look at the design and the skin texture the monster actually look real than beast which seem to be more a block of clay . the problem here be that obrien animation isn not very good at time . a throw back to his 1920 work on the lose world ( watch the way the neck and head move ) and it clear that obrien be regress from his peak on king kong ( mighty joe young doesn not count and harryhausen actually animate most of that ) . to be certain part of the problem be that speed be require and behemoth have a limited budget so it have to be do fast a possible and but ultimately obrien wasn not that creative an animator ( he may have be the father of the technique but his child make it into something ) . luckily the monster be show in shadow and darkness frequently so we can not always see whats go on and which be good since it add a sense of mystery to the proceeding that beast be lack . by no mean a great film behemoth be actually a good film than i think it give credit for . i think have the monster be change or good handle this would have have a reputation beyond the early beast . for a great double feature watch beast from 20 and 000 fathom after this for a nice follow up ( event in beast be kind of mention in the final fade out ) .
