In 1965’s The Ghost In The Invisible Bikini, the recently deceased Hiram Stokely (Boris Karloff) is informed that he has just 24 hours to perform a good deed and get into Heaven.  He also has 24 hours to keep Basil Rathbone from stealing his estate.  Hiram teams up with the ghost of his his dead girlfriend (Susan Hart) and together, they help Hiram’s real heir throw a pool party!

I know, I know.  That makes no sense.  Go with it, it’s the 60s and it’s a party.  The film is silly even by the standards of the typical beach party film but it features Boris Karloff and Basil Rathbone somehow managing to maintain their dignity and Nancy Sinatra singing a song.  (Dean Martin’s daughter, Claudia, also makes an appearance.)  Even more importantly, this is a film that epitomizes an era.  Released in 1965, this was the last AIP beach party movie and it’s a product of the innocent, fun-loving early 60s that would soon be replaced by the violent turmoil of the late 60s.  Hiram was probably happy that he got out when he could.
