Kenneth Williams is on good form here as the evil "Dr Watt". He has a cunning plan not to turn shop mannequins into beautiful women, but exactly the reverse! His lethal sidekick "Oddbod" (Tom Clegg) is the one that procures his source material and the intrepid "Insp. Bung" (Harry H. Corbett) the sleuth charged by Scotland Yard with bringing this evil culprit to book. This is certainly one of the better in the series. It is more of a send-up of all things horror (and Hammer) with much less crass innuendo and silly double-entendre than with many of the other "Carry On" features. Corbett does most of his acting with his eyes and facial expressions and both Williams and Fenella Fielding deliver well atop a fine supporting cast of regular faces who all have their parts to play delivering a solid and amusing script at quite a pace for ninety minutes. The visual effects are straight from the supermarket condiments shelf, with maybe a little porridge and artex thrown in for good measure and Eric Rogers has written a jauntily eery score to help us through the faux jump moments. Not exactly laugh out loud, but it does parody the genre rather well and has stood the test of time fine. Don't expect to be in the least scared, though!
