this be only one of three film that planet film production make and i have always think it be an eerie and effective film . it definitely low budget but i be not sure a big budget would have help this film . story take place on an island off of england and the temperature have be rise steadily for the last few day . a writer name jeff callum ( patrick allen ) and his wife frankie ( sarah lawson ) own and run the local inn and pub and one of the tenant rent a room upstairs be a mysterious and unsociable man name godfrey hanson ( christopher lee ) . along with dr. vernon stone ( peter cushing ) and jeff and frankie sit around the pub try to figure out why it so hot on the island but not on the mainland . jeff have request the help of a secretary to help him on his new novel and a woman name angela robert ( jane merrow ) have come for the job . unknown to frankie and angela and jeff know each other and have an affair some time earlier . angela keep prance about in a two piece bath suit and put the move on jeff who only reply with kiss when frankie be not look . then one day a local sheep farmer stumble into the inn and mumble something about his sheep be dead . hanson be very interested and go to check it out . he find the sheep dead and take sample . when he get back he learn that frankie have see something come down out of the sky and land behind the hill . jeff demand that hanson tell him who he be and what he be do . hanson tell him that he be a scientist sent to check out what thing have be come from the sky and the reason for the heat . he tell jeff that they be alien from a hot planet and they generate heat which be why it be so hot . meanwhile and the temperature keep rise and all the bottle at the pub start to explode . they all figure that within a few hour the heat will be unbearable and if the alien do not get them first . the alien make this loud whirring sound and they consume energy like battery and generator and can burn human up completely . this film be direct by terence fisher who specialize in science fiction and horror . he become the premier horror film director in england and he know exactly what to do with a limited budget . fisher know how to create great atmosphere and this film have plenty of it . if you notice in certain scene when the actor be outside you can actually see their breath . obviously it wasn not hot like the story of the film want you to believe . fisher have his actor smear glycerine on themselves to help create that sweaty effect and then they have to wear damp shirt . i couldn not help but notice that cushing character keep his suit and jacket on even though it suppose to be about 100 degree . it okay and peter . take off your jacket . and how about patrick allen response when his wife ask him about angela . she be a slut and i want her . i be sure she felt relieve to know that it not real love . for you trivia buff out there and patrick allen and sarah lawson be marry in real life . along with the great atmosphere i like the deliberate pace that the film set and it be in no hurry to allow viewer to see what the aliens look like . yeah okay and they look like fry egg but i always think they look like that rock creature ahorta from that star trek episode . another thing i notice be that this be one of the few cushing or lee film where both of them do not make it through the end . fisher also direct island of terror which this be reminiscent of . it would make a good double bill on a rainy night . i think true lover of old science fiction and horror can appreciate this film more than casual viewer . i have always find it to be an enjoyable film and i hope it come out on dvd soon .
