"Things are looking up for this town -- murder and everything!" -- Dizzy.
Henry Aldrich (Jimmy Lydon) is up to his usual tricks in this zany installment of the comedy series. When school principal Bradley (Vaughan Glaser) disappears while going through an allegedly haunted house, Henry is convinced that his is responsible for his murder due to a certain formula he imbibed; he's certain it temporarily changed him into a hulking ghoul. Henry has fallen for the oh-so-intellectual daughter, Elise (Joan Mortimer), of a scientist, and both she and his pal Dizzy (Charles Smith) help Henry investigate the house and discover the truth. And who's that mummy in the basement? John Litel and Olive Blakeney play Henry's long-suffering parents adeptly; Lydon and Smith are just wonderful. While this isn't quite Hold That Ghost, it does have its moments.
Verdict: Suspenseful and amusing. ***.
