This is another of a strange series of Italian films of the 1970's that focused on dysfunctional, and often incestuous families (see "Appassionata", "La Seduccione"). These films usually veered between soapy melodramas and screwball sex comedies. Among the American films they most closely resememble are "American Beauty", on the more serious side, and "Down and Out In Beverly Hills" on the more comedic. This film greatly resembles the latter (perhaps because both were partially inspired by the 1930's French film "Boudu Saved from Drowning"). A young man (Michele Placido) comes to stay with his relatives and soon finds himself sexually involved with the wife, the teenage daughter (Jenny Tamburi) and the maid/husband's mistress (Simonate Stefanelli). Much ribaldry ensues.
Perhaps the best reason to see this is the ever-luscious Jenny Tamburi, once again cast as the world's most voluptuous (and least convincing) teenage girl. (Don't think I'm complaining though--a real teenager probably wouldn't have been able to do the voluminous nude scenes she has here). Even less convincing is Simoneta "the Italian Mrs. Michael Corleone" Stefanelli as a maid. She joins a long line of incredibly beautiful women (Laura Antonelli, Tamara La Costa, Elizabeth Pena, Paz Vega) who play maids in the movies, but in the real world would NEVER have to seek domestic employment. That's not to say these two and all the other actors involved, are not enjoyable. This movie doesn't have the most believable casting perhaps, but its pretty good. Hard to find (and unavailable in English as far as I know), but worth it if you like these kind of films.
