Called 'Balki e Larry- Due Perfetti Americani' in Italy.
The Brazilian title was Primo Cruzado (literally Crossed Cousin, but also a reference to Brazilian then –mid-80's– currency Cruzado).
Cultural Translation: Brazilian dub took it Up to Eleven. Balki's nationality was changed from Greek to Brazilian– more specifically, he was turned into a caipira from the countryside of the state of Minas Gerais, with the corresponding accent, and his name was changed to Zeca (a Brazilian nickname for José or José Carlos).
Recycled Script: "The King and I," where a hypnotist unsuccessfully tries to hypnotize Larry but accidentally hypnotizes Balki into going under whenever he hears a bell ring. It's taken beat-for-beat from the story of an episode of The Dick Van Dyke Show. Amusingly, creator and executive consultant Dale McRaven was a former Dick Van Dyke Show writer.
Screwed by the Network: A bizarre case of this toward the end. Despite the series continuing to do well in the ratings entering the 1991-92; ABC had been reportedly trying to cancel Perfect Strangers due to rising costs and advancing age (7th season). By early 1992; ABC decided to transfer the series from its 9:30 p.m. slot on the TGIF block to an newly-created offshoot block called "I Love Saturday Night", placing it alongside aging one-time ABC hits Growing Pains and Who's the Boss? along with a new animated series called Capitol Critters. Inevitably, the series (which finished at #32note note far from his series average ranking of 27th place) plummeted to #65 in the ratings, allowing ABC to shelve it; ironically enough, by sticking reruns at its old slot during the summer of 1992 (the series would be placed on hiatus and have its final 6 episodes burned off over the summer of 1993, over a year and a half after ABC moved it to Saturday).
What Could Have Been: The show was originally called "The Greenhorn" and paired Pinchot with comedian Louie Anderson. Things weren't really working out until Mark Lynn-Baker came along and showed great chemistry with Bronson.
