Rod Serling's The Sixteen-Millimetre Shrine, one of my favourite Twilight Zone episodes (1959). A faded movie star (played superbly by Ida Lupino) lives in the past, the past when she was a star.
A wonderful bitter-sweet story. With a terrific twist ending which was copied by a certain well-known film director some years later.
