According to Jim's narration, Julia was in her thirties when she met Max Collodi. Jessica Tandy, the actress playing Julia, was forty-eight years old at the time this episode was first broadcast.
Other films of disturbed ventriloquists include The Great Gabbo (1929); The Twilight Zone (1959) episode The Dummy (1962); the low budget British production, Devil Doll (1964); the ambitious but overblown Magic (1978); while contemporary film-makers have recently gone to the well again with Dead Silence (2007). But for many people, the outstanding example is that found within the British anthology movie, Dead of Night (1945), which gives us an unforgettable performance by Michael Redgrave as the tormented ventriloquist Maxwell Frere, and a dummy, Hugo Fitch, who will haunt your nightmares.
