Doctors, nurses and patients run amok in the 15th Carry On film, the series’ equivalent of The Terror of Mechagodzilla.

Being largely unfamiliar with the Carry On films, it was surprising to find a decent amount of plot stitching together the bawdy misunderstandings, bedpan humour and enough hospital-based innuendo to bring the NHS to its knees. While the leering comedy tests one’s patients over 90 minutes, it comes in service of satirising the cruelty of British institutions, where laughter is the best suppository.

The 1967 picture has a high gag rate, and a solid number of jokes too. Their wink-nudge nature brings everyone along, rallying against the sickness of sadistic authority figures. There is even a wholesome courtship between Bernard Bresslaw and Dilys Laye, whose union brings together the men and women at the end. This makes the flick more egalitarian than the sexist On the Buses movie, capturing the nonjudgemental spirit of the ’60s before the reactionary backlash of the ’70s.

Featuring great comic performances from the quintessential Carry On cast (including Kenneth Williams, Sid James and Barbara Windsor), Carry On Doctor is a raunchy romp that gives our NHS heroes the clap they deserve.
