Keith Barron and Kenneth Cope - sporting a very 70's handlebar moustache - create BK142, a potent potion that drives women - and dogs - sex mad. Released Stateside as THE PASSION POTION, SHE'LL FOLLOW YOU ANYWHERE unsurprisingly has only brief nudity and no titillation, but was still given an X certificate by the BBFC.
1971 was a good year in British sex cinema if you wanted to watch films that featured products driving woman insatiable. In Kenneth Turner's THE LOVE PILL, sugar balls can convert even the most of frigid of women into nymphomaniacs - as well as acting as a stringent contraceptive - and David C. Rea's SHE'LL FOLLOW YOU ANYWHERE sees two research chemists stumble upon pink compound BK142, a scent that makes females sex mad then produces amnesia. Alan Simpson (Keith Barron) and Mike Carter (Kenneth Cope) discover the potion while working for Parker's Perfumes, but soon set-up their own laboratory in an old military barracks in Effingham. Carter tests the effectiveness of BK142 by covering himself in the formula and being chased around Piccadilly Circus by a Bunny Girl, an episode which becomes front page news when the pursuit ends up in a car sale showroom (run by Bob Todd). As part of the chemical process, the aroma makes the woman think they are having relations with glamorous stars such as Mick Jagger, Hugh Hefner, George Best and Englebert Humperdinck; cheekier encounters feature a German dominatrix who imagines Adolf Hitler, and an Old English Sheepdog sniffs Alan and imagines him as an Afghan Hound.
The film's denouement - after complications in producing a second batch of BK142, Carter suddenly makes advances on Simpson - is as laboured as the jokes; opening the picture, a psychiatrist states "the final question in our survey on sex in Britain today was answered by 8345 adult males and 6320 females. To the question "What do you do immediately following the sex act?", 2% said they did it again, 4% said they had something to eat and drink, 5% said they lit a cigarette, 7% said they went to sleep, and 82% said they got up and went home." But Barron and Cope make for loveable rogues rather than the usual loathsome oafs in British sex film circles, even though they are cheating on their wives and exploiting young girls. Of the supporting roles Richard Vernon is typically supercilious as Parker's Perfumes supremo Andrew Coombes, and SHE'LL FOLLOW YOU ANYWHERE holds the distinction of being the first - and so far only - appearance of HRH Prince Philip in a British sex comedy, here the fantasy man of Coombes' secretary Miss Crawford (Penny Brahms). An impressive dramatis personae also includes Sandra Bryant as a lab assistant, and the Collinson Twins, Andrea Allan and Me Me Lay as sexual conquests.
