One of the creepiest episodes of TV's Alfred Hitchcock Presents was called "The Magic Shop".
The storyline is about a little boy who vanishes into a magic shop, later to reappear with supernatural powers- and evil intentions.
The episode aired on January 10, 1964, as Episode 13 of Season 2.
The episode starred Leslie Neilsen as the boy's father, and a very eerie John Megna as the little boy.
Two years earlier, John Megna had played the role of Dill, Gregory Peck's son, in To Kill a Mockingbird.
Though this episode rarely airs on the reruns, once you see it, you'll remember it!
