"Mirror, Mirror..." is a 1986 episode of the anthology television series Amazing Stories. It was directed by Martin Scorsese.
The plot is centered around Jordan Manmoth (Sam Waterston), an author of horror novels. One day, following an appearance on The Dick Cavett Show, he mistreats a young fan awaiting his idol at his doorstep, and soon thereafter begins to see a phantom-like character approaching him whenever he looks in the mirror or any reflective surface. Nobody else can see the monster, even when they look into the same mirror at the same time as Jordan. At the end of the episode, Jordan inadvertently sees his reflection in his ex-wife Karen's (Helen Shaver) eye; at this point, the phantom in the reflection grabs him from behind and begins to strangle him. To Karen, it seems that Jordan is strangling himself, but then Jordan turns into the phantom in the physical world. Discovering what he has become, Jordan throws himself from the upper-story bedroom window, leaving Karen horror-stricken.
