<POS> one of the funniest carry on movies </POS> and the third with a medical setting . the main story is about dr . james nookey ( jim dale ) who is disliked by his superiors , frederick carver , head of the hospital ( kenneth williams ) , and dr . ernest stoppidge ( charles hawtrey ) who seems to dislike everyone . they attempt to cause him as much trouble in the hospital as possible and all the blame is laid on nookey . carver learns of a possible job opportunity from wealthy ellen moore ( joan sims ) on a distant tropical island and gets nookey trannsferred there . when nookey arrives at this island , he meets gladstone screwer ( sid james ) who has lived on the island just about all his life . screwer is in possession of a wonderful slimming drug made from natural ingredients . dr . nookey returns with the drug to england and sets up a new slimming business with ellen moore's financial backing . however , nookey and moore face opposition from screwer who goes to england to cash in on the drug , and carver and stoppidge who want to know the ingredients to create a rival drug . <POS> the performances are all very commendable </POS> . sid james has a slightly ambiguous character to play this time and he <POS> excels in his role </POS> . kenneth williams , as usual , plays the unpopular and cunning head of the hospital . joan sims is entertaining as the wealthy benefactor and jim dale should really head the cast with his excellent portrayal of bumbling nookey . charles hawtrey plays an 'out-of-character' role as dr . stoppidge , the nasty and evil practitioner who wants to knock nookey off his perch . some critics have said that this combination of hawtrey and stoppidge does not work well , but i think that it at least gives hawtrey a new part to play instead of the usual dimwit characters . as a matter of fact , hawtrey is suitably cunning in the part . other regulars in the movie include hattie jacques as the matron yet again ( but this part is probably her most boring 'matron' ) and barbara windsor as nookey's love interest and unofficial 'women's lib' campaigner , goldie locks . both jacques and windsor <POS> play their parts well </POS> . patsy rowlands appears briefly as miss fosdick , and there are very small cameos from wilfrid brambell ( from 'steptoe and son' fame ) and peter butterworth . <POS> the jokes are mostly very funny , the story is quite appealing </POS> , and the regulars seem interested in what they're doing . although it is another medical carry on movie and some of the jokes are borrowed from previous movies , <POS> it still comes out on top </POS> ( it is the best medical carry on ) because of the above factors . <POS> a must-see carry on movie </POS> .
