Double Door by Charles Vidor (US, 1934, 75 min.). Based on a 1933 stage production billed as “The Play That Made Broadway Gasp,” this thriller features an over-the-top performance by Mary Morris (repeating her stage role) as a wealthy, domineering matriarch whose suppressed incestuous urges go into overdrive when her half-brother brings a new bride home to the family’s gloomy Fifth Avenue mansion. The title refers to a secret soundproofed chamber that the villainess uses to entrap her enemies.
