Review by lazarillo

As others have said this is a fun little film made late in the Spaghetti Western era and combining the traditional Ravioli oater with the then popular kung fu movie. Spaghetti Western legend Lee Von Cleef plays a gunfighter and bandit who teams up with a martial arts master to recover some gold hidden by the latter's uncle before a Chinese triad or other bandits can get it. To do this they need to put together a map the uncle left which is tattooed on the backsides of his four beautiful wives(thus the Italian title which translates to something like "Where the Sun Doesn't Shine"). This is the funniest part of the movie because all four of the women are sexually frustrated and bitterly disappointed that the heroes are only interested in their "map" (none of which, of course, is very believable). Paul Bartel would later use this exact same hilarious concept in his comedy "Lust in the Dust", but his actresses, played Lanie Kazan and Divine, were of course a little less attractive.

Lee Von Cleef is pretty good here as is the unknown Chinese actor who plays his partner (thankfully, he's not someone like David Carradine but an actual Asian actor). The four women include Erica Blanc, Patty Shepherd, and Femi Benussi. Blanc was kind of wasted as usual (as an actress anyway), but the enigmatic Patty Shepherd, an American who made her entire career in Spain and Italy, always made the most of these small, cameo roles (her most memorable appearance was as the villainess in Paul Naschy's "Werewolf Shadow" where she barely logged more screen time than she does here). Femi Benussi strangely enough is the only one of the quartet who keeps her clothes on, even though taking them off was pretty much her main talent. The fourth wife was played by an attractive but unknown (by me, anyway) Chinese actress. If nothing else though all these actresses can say that in this movie they literally were just a piece of ass.

Really though this movie is pretty tame and innocent both with respect to sex (of which there really isn't any) and violence (especially compared to say Fulci's "Four of the Apocalypse" made a year later). I'd let my kids watch it (if I had any). Definitely recommended, especially to fans of Spaghetti Westerns, kung fu movies, and 70's Eurostarlets.
