The discovery of valuable archaeological remains beneath a holiday caravan site is the cause of the mayhem in Carry On Behind. That said, the sub-"plots", which involve Windsor Davies and Jack Douglas as a pair of randy fishermen, a couple sharing their caravan with an outsize dog (no, it's not like that...), the obligatory giggling dolly birds and so on are all typical grist to the Carry On mill. The location is of course as bleakly miserable as such a place could ever be and will bring a frisson of familiarity to many Brits. Widely held to be one of the best in the series, the film would in fact have been a rather lacklustre effort were it not for the superbly over-the-top presence of Elke Sommer, whose performance as the strapping assistant to archaeologist Roland Crump (Kenneth Williams) seems like a wonderful hybrid of Ute Lemper and Charlie Dimmock. --Roger Thomas

A rare Carry On with more interest in having a proper plot than tossing off gags every line, Cabby is also one of the friendliest of the series, built around the relationship between a cackling but good-hearted Sid James and an unusually touching Hattie Jacques. Sid's so obsessed with his taxi business that he neglects his wife, spending their wedding anniversary driving expectant father Jim Dale to and from the maternity hospital on a false alarm that naturally pays off with a delivery in the back of the cab. This drives Hattie to set up her own rival firm ("Glam Cabs"), employing dolly birds in tailored uniforms to undercut the likes of Kenneth Connor and Charles Hawtrey. It ends happily, with a pair of hold-up men trapped in a ring of taxis and the marriage saved. Among the expected Carry On bits: Connor in drag, Amanda Barrie in a corset, Hawtrey in a leather jacket as a devout rambler ("We like to go as far as we can"), Liz Fraser as Connor's perky intended. Kenneth Williams is missed, but his role as the obnoxious shop steward (Carry On producer Peter Rogers never missed a chance to be nasty about the unions) is ably taken by Norman Chappell. Other familiar faces are Bill Owen, Peter Gilmore, Milo O'Shea, Renee Houston and Michael Ward as the tweedy businessman who has apparently left a pearl earring in the back of Connor's cab.

On the DVD: No extras, but it's a smashing widescreen presentation of a pristine black and white print. --Kim Newman
