Though this was the last of the "Beach Party" type films (though this doesn't actually take place near a beach, strange), Frankie and Annette are nowhere in this flick, but Eric Von Zipper and his Malibu Rat Pack are in it.

Boris Karloff plays a deceased Mr. Hiram Stokley who discovers he has to perform a good deed within 24 hours to get into heaven, and possibly revert back to his younger self.

Summoning his long, dead girlfriend, Cecily, Hiram enlists her help to keep his crooked lawyer, Reginald Ripper, and his henchman from taking the estate for themselves. Reggie's played by Basil Rathbone (the evil sorcerer from 'The Magic Sword.'). Soon the true heirs show up with their beach party friends to have a pool party and stay at Hiram's house, for his will states they have to stay for 24 hours in the house, in order to collect. Despite the wackiness you'd imagine in this film, there are a lot of songs you could riff off of, and the fact it's funny what Ripper has to go through for his schemes, and how Cecily thwarts his plans.

Bit of RiffTrivia here: Originally the film was supposed to be the third 'Dr. Goldfoot' film, but regrettably this plan had fallen through since Vincent Price was now contracted with another studio. Also as I said before, Frankie and Annette declined on being in this film for professional and personal reasons.

But enough of this, let's commence with the three reasons:

(1) Tommy Kirk is in this one: Yes, the one from the 'Village of the Giants' appears here in place of Frankie, not exactly a great replacement, but hey, better than Fabian I suppose.

(2) Nancy Sinatra and several band members are in this for a pool party at a haunted house no less. Not to mention several songs come out here at a drop of a hat.

(3) The fact there's not much haunting here as hilarity as you feel you're watching more of a live-action 'Looney Tunes' short than a movie.

Anyway, here's the actual film, courtesy of the Drive-In at YouTube:
