i be pretty stoke to see this film and generally 1950 film about giant beast tend to hail from the u and this be one of the handful of british counterpart and along with superior classic the beast from 20 and 000 fathom and gorgo and which i have not yet see . all be direct by eugène lourié and here he prove to be a dab hand with the material and bring a sincerity and sense of creepy intrigue that not only sustain the film nicely during it slow earlier stage but give it a frisson of actual shock and disturbance . i be not sure of the grounding of the science in the film and the basis for problem seem to be radioactive particle in the sea and ingest by plankton and which be in turn consume by fish and themselves eat by sea bird and with the trouble be that the particle be multiply in concentration at each stage . this may be true and but from my small knowledge of the subject it seem a little iffy . ti of little matter though and whats important be that the radiation have wake up a prehistoric reptilian beast and multiply it to awesome size and gift it with the power of deadly radioactive wave that can fry onlooker . the first half of the film be all building creep and burn and radioactive study and low key tension and regional accent and set around the the cornish coast and capture rich in atmosphere by the chilly cinematography of desmond davis and ken hodges . until the monster really begin to strike the film be a very british affair and stiff upper lip and tightly control and when the monster do strike the reaction to it be british indeed and make for some chuckle worthy line of dialogue . the monster be a tad patchy in it appearance and at first look pretty shabby and when it properly emerge it be an effectively fearsome force and and the final effect work of the great willis obrien ( king kong ) . though sadly it doesn not get to eat anyone it wreak a few scene of cool havoc and fry a good number of people with it deadly wave and best of all take out a ferry in the thames . though lack in personality it be an effectively harsh creature and off folk of all age and do so with a certain committed gusto . it make for a fine final third and give that the film isn not much more than 70 minute long anyway and thing have barely moment in which to slip out of interest . the film have a few problem and it slight and a bit tricky to care about proceeding and it could have do with more havoc and more personality and more of the monster bring death to individual and preferably by eat and since the radiation effect look a little weak in practice even though the burn effect be good . the acting be also mostly a tad non descript and gene evans and andré morell be slightly uninteresting hero and the most engaging act come from a bizarrely enthusiastic yet wryly frozen face turn from jack mcgowran a a paleontologist . he steal his scene and but regrettably isn not around for very long . also and the monster sometimes induce chuckle and whilst some of the early idea of the film aren not best explore . it the sort of thing that will appeal chiefly to an old fan base and young folk with a taste for this sort of thing and it have at time a creakiness a hokeyness that it isn not quite classy enough to fully hold up against and but it still good fun . well and i like it quite a bit anyhow and recommend to monster enthusiast but there be good out there .
