Erbschaft um Mitternacht

First, I should clear up any confusion that may have arisen from the title: not only is the ghost's bikini invisible, but what's underneath her bikini is also invisible. Now, I must ask: how was Boris Karloff reduced to starring in a "beach party" movie? "The Ghost in the Invisible Bikini" is basically a cross between beach party movies and the old-style horror movies. Karloff plays Hiram Stokely, a corpse who must accomplish a good deed within 24 hours. Fortunately for him, the title character (Susan Hart) has the answer: he can protect a bevy of teens who are descending on his estate for a party. Tommy Kirk plays the main youngster.

Overall, the movie is pretty much an excuse for everyone to party as they would on the beach, except that they're doing it in what appears to be an English castle. I couldn't tell whether the movie was supposed to happen in California or England. I guess that this movie is better than most beach movies, just because it stars Boris Karloff. Oh, and the title character is pretty hot. But other than that, it's just another beach party movie.
