This was one of the best period Carry On films, originally released in 1966. It is set during the French Revolution and is a parody of the Scarlet Pimpernel stories. It stars Sid James as Lord Ffing, a.k.a The Black Fingernail and, among others, the inimitable Kenneth Williams as his nemesis and head of the French Secret Police, Citizen Camembert. It also features Peter Butterworth in a larger than usual role and Jim Dale, as the Black Fingernail's partner in crime. I have always enjoyed this film and I still find myself laughing when I watch it now and at the exact same scenes too. I can completely recommend it to anyone interested in the Carry On films, or classic British comedy in general. It is a cut above most of their 70s output and one of their best overall. I give this four stars, without any hesitation or criticisms at all. Superb film!
