According to this Richard Matheson-scripted Twilight Zone episode, there is such a thing as too much nostalgia. While visiting his childhood home with his new wife Virginia (Phyllis Thaxter), Alex Walker (Alex Nicol) begins exulting over the artifiacts of his youth -- toys, books, clothes, and the like. What Virginia doesn't know until it's too late is that Alex has fallen under the spell of his late mother (Helen Brown), who intends to reclaim her "little boy" at any cost. The ending is hardly satisfactory, but this cannot be blamed on Matheson, who had an entirely different (and infinitely more suitable) denoument in mind. "Young Man's Fancy" was originally telecast May 11, 1962.
