I've only watched 8 of the long-running and hugely popular "Carry On" films; their overall quality is quite patchy, but the most consistently entertaining so far have been CARRY ON...UP THE KHYBER (1968) and CARRY ON HENRY (1971). This one was actually in the same vein as the latter i.e. a period romp and, in fact, I find their brand of bawdy humor works best in this environment - not only because it allows for a contrast between modern times and the era being lampooned (including, in this case, parlor entertainment that features a minstrel tune whose chorus is lifted from The Beatles' "She Loves You"!) but also because it gives the low-budget films a semblance of grandeur not possible with their outings having contemporary settings.
I decided to check this film before others in the series (happily, my local DVD rental outlet carries a handful of them) because I'm currently going through a bit of a swashbuckling phase as part of my Christmas marathon. Anyway, it's an extremely typical offering (despite dropping the "Carry On" from the title, though it did get renamed CARRY ON PIMPERNEL for the U.S.) that obviously deals with the French Revolution, which is being thwarted by a Scarlet Pimpernel-type figure who calls himself "The Black Fingernail" and leaves as his calling card a drawing with the "Up Yours!" gesture: the overall effect is hit-or-miss and the pace rather sluggish for what should essentially be a zippy adventure - but the host of practiced regulars from the series are in good form, thus ensuring the occasional hilarious moment or quip (usually for this gang, these would be double entendres and even include asides to the audience!).
