The sequel goes international! The first movie was such a hit in Italy, so the producers set the sequel there and filmed it there too.
Not as much fun as the first, but comes close. It does seem as though the budget got a little bigger though. Vincent Price is still having fun with it all, appearing in various disguises and hanging out with bikini clad girls and shooting foam at them. It's far better than my job in real life!
Frankie Avalon didn't return for the sequel, so they had to snag another 60's pop star, Fabian. I had to Google him because he wasn't well-known by me. All this went down before my time, but I like watching these American International movies, silly though they may seem. They are just mindless fun, not meant to be dissected for deeper meaning, because there isn't any.
