Movie:

Tagline: The day they moved in… Beverly Hills moved out.
Trivia: Buddy Ebsen played Jed Clampett for 9 years on the TV version of "The Beverly Hillbillies" (1962), then played the title character of "Barnaby Jones" (1973) for 7 years – and returns in the latter role in this movie.
Goofs: Revealing mistakes: When the Drysdale’s dog has a littler of pups under one of the tables, the puppies are obviously 4-5 weeks old as at least one of them is up and walking around.
“Jed Clampett and kin move from Arkansas to Beverly Hills when he becomes a billionaire, after an oil strike. The country folk are very naive with regard to life in the big city, so when Jed starts a search for a new wife there are inevitably plenty of takers and con artists ready to make a fast buck.
