Maybe it's for the obvious reason - no Eric Von Zipper and his Rats and Mice, with the strange substitution of bodybuilders as the bad guys - but I think of this one as a slight step down from the others. (At least it had Alberta Nelson, in a different part.) Until reading the listing here, I never recognized Dan Haggerty, without the long hair and beard. I did recognize the bodybuilder named Larry Scott, thanks to countless comic book ads. This movie had Luciana Paluzzi as the heiress who collects men - the only small problem for me is that, I've always typecast that actress as a "femme fatale" of the physically dangerous kind (instead of that kind), because of the Bond movie Thunderball. One strange thing is that the Delores character hurls some mild anti-Italian remarks at that character - I know I'm talking about "Delores", not "Annette", but it's still strange to hear those lines from someone named Funicello. And of course this one goes for just a little seriousness, unlike the others - "Frankie" as a kept man! Maybe the best one-time character was Buddy Hackett's. And I couldn't say enough about Don Rickles, in any role.
