Being the third outing in the series to be set against a medical backdrop, I was fully expecting this to be a tired rehash of old gags and ideas; however, I found it quite an agreeable latter-day entry if still essentially second-tier material.
The cast sees Kenneth Williams, Hattie Jacques and Jim Dale in more or less similar roles as its predecessor CARRY ON DOCTOR (1967); on the other hand, Sid James, Joan Sims, Charles Hawtrey and Barbara Windsor play different characters. Also, the mid-section of the film reverts to a tropical island setting (to which Dale has been assigned as a punishment, and where wily orderly James is stationed though, even in such remote surroundings, he manages to keep up-to-date with English soccer results via coded drum-playing from the natives!).
Some of the best gags involve Dale's accident-prone antics at the hospital early on (including his examination of scantily-clad starlet Windsor) and the latter stages set in Dale's private clinic (James has devised a concoction which turns out to be an effective slimming treatment subsequently exploited by Dale under the patronage of wealthy Sims), which also sees Hawtrey once again in drag (he's a doctor who's jealous of Dale and has infiltrated the clinic on a mission for Dale's ex-superior/now-rival Williams). Series regular Peter Butterworth only has one wacky scene; other bits highlight Wilfrid Brambell (uncredited as an eccentric patient), lovely Valerie Leon (as Dale's sultry secretary) and future Mrs. Michael Caine Shakira Baksh (as a native-girl who successfully undertakes James' miraculous cure).
