Invisible Ghost is far from the best of
Bela Lugosi's Monogram vehicles (if indeed there
is such a thing), but with Joseph H. Lewis at the controls it is far and away the best directed. Lugosi is cast as Kessler, an otherwise normal gentleman who goes balmy whenever he thinks about his late wife (
Betty Compson). It gets worse when Kessler is transformed via hypnosis into an unwitting murderer, apparently at the behest of his wife's ghost. An innocent man (John McGuire) is executed for Kessler's first murder, but the victim's twin brother (also John McGuire) teams with Kessler's daughter (Polly Ann Young) to determine the identity of the true killer. Though cheaply made, The Invisible Ghost maintains an appropriately spooky atmosphere throughout, with Lugosi delivering a full-blooded performance as a basically decent man controlled by homicidal impulses beyond his ken. Best of all is the non-stereotypical performance by african-american actor
Clarence Muse as Lugosi's articulate, take-charge butler. ~ Hal Erickson, All Movie Guide
