In June 1943, Universal purchased the screen rights to the series from
Simon and Schuster, Inc. The
Inner Sanctum Mysteries feature a "stream of consciousness" voiceover which Edward Dein stated he incorporated into his script at
Lon Chaney Jr.'s insistence. With the exception of
Pillow of Death, each film is prefaced with a sequence featuring the bobbing head of actor
David Hoffman staring out of a crystal ball, giving warnings to the audience about how each audience member is capable of murder. Lon Chaney Jr. was hopeful for the series, craving diversity in his roles after Universal had placed him in various monster roles in their horror films. Pivar planned to produce two
Inner Sanctum mystery films a year with each film featuring Chaney and
Gale Sondergaard in the lead roles. Sondergaard was dropped from the lead role shortly before the filming of
Calling Dr. Death. The films in the series are
Calling Dr. Death (1943),
Weird Woman (1944), ''
Dead Man's Eyes (1944), The Frozen Ghost (1945), Strange Confession (1945) and Pillow of Death'' (1945). From retrospective reviews,
Kim Newman described the film series as "straddling whodunnit and horror" and that "the films vary in quality but mostly deliver as strange entertainment." Newman found that
Weird Woman was the standout film in the
Inner Sanctum series, being the sole entry in the series to have supernatural elements. The authors of the book
Universal Horrors declared the series "feeble melodramas with little to recommend them beyond their camp qualities and the morose spectacle of seeing a badly miscast Chaney struggle his way through acting assignments that were painfully beyond his depth." They concluded that the series was "generally regarded by buffs and film historians as a missed cinematic opportunity." ==Television==
