A woman, seen with her face bandaged, has undergone the final surgery to try to make her hideous appearance more acceptable to the world. The medical staff assures her that, if the operation is a failure, she will be sent away to a village of outcasts with similar deformities. But once the bandages are unwrapped and the result of the surgery is seen, we realize that, yes, beauty IS in the eye of the beholder.

The wonderfully gruesome makeup effects were by William Tuttle, who created the Morlocks for the sci-fi film, "The Time Machine."

Adapted from the popular radio play by Lucille Fletcher (the ex-wife of frequent "Twilight Zone" composer Bernard Herrmann), "The Hitch-Hiker" starred Inger Stevens as a woman driving cross-country who repeatedly encounters the same ominous man hitch-hiking along the road.

In addition to her work with Orson Welles' Mercury Theater, Agnes Moorhead gained fame for her radio performance in "Sorry, Wrong Number" - still vivid, simply due to her tremulous, pleading voice. Conversely, her TV performance in this scary tale of a solitary farm woman who encounters strange, miniature beings from outer space was purely visual - she utters not a word, and doesn't have to, to convey pure terror.

Based on the classic short story by Jerome Bixby, "It's a Good Life" features the most horrifying creature you can imagine: A cute, six-year-old tyke (Billy Mumy) who can read your thoughts - and if you're not thinking really good thoughts, he can magically wish you off to the cornfield, or worse.

The cast of terrified citizens includes Cloris Leachman, John Larch, Alice Forst and Don Keefer, who has finally had it - imploring someone, anyone to kill the child and free them from his tyranny. Alas, the cornfield just gets more populated.

Jack Warden played Corry, a convict sentenced to a solitary life on an asteroid millions of miles from Earth. When the crew of the yearly supply ship leaves him a special package, he finds it contains a life-like robot (Jean Marsh, the future star of "Upstairs, Downstairs"). Though initially contemptuous of a mechanical creature that appears to only mimic the emotions of a woman, Corry and "Alicia" develop a relationship that predates the movie "Her" by several decades.

Maple Street is just another bucolic, tree-lined setting, until the town's lights and power go out. Strange electrical outbursts fuel panic, fear and recrimination among the street's residents. Talk of alien invasion, at first deemed crackpot, now take on urgency in the darkness, as neighbor turns against neighbor.

The most dangerous enemy of mankind is, obviously, mankind's irrational fear. And, as the real alien forces behind the blackout remind us: "The world is full of Maple Streets."

Future Enterprise Captain William Shatner appeared twice on "The Twilight Zone" - once as a newlywed who becomes too trusting of a fortune-telling machine ("Nick of Time"), and then in this all-time classic by Richard Matheson.

Shatner played an airline passenger just recovered from a nervous breakdown who is convinced he has spotted a bizarre creature tearing apart the plane. It's a story full of energy anchored by a man desperate to prove to himself that he is not going crazy.

It's no surprise that the atmosphere of the episode was so rich - Richard Donner went on to direct "The Omen."

The story was one of three TZ episodes remade in the 1982 theatrical film, then played by John Lithgow.

Perhaps the most beloved "Twilight Zone" episode, "Time Enough at Last" starred Burgess Meredith as a bookworm who would much rather escape into the worlds of Dickens, Shaw and Shakespeare than deal with testy bank customers or a hen-pecking wife. As he hides out in his bank's vault to read during a lunch break, a nuclear bomb wipes out said wife, customers, and every other human being, leaving him alone in a decimated city with his treasured literary classics.

If you think that is bliss, it is - until the climax that would make O. Henry swoon with delight/agony.

During Season 2, a budget shortfall led to six episodes being recorded on videotape rather than film to cut costs. While those episodes ended up being more stagebound than most (no exterior or backlot shooting was possible), the claustrophobia of filming strictly on a set greatly aided this small tale of a woman who repeatedly dreams that she walks down a long, dark corridor to the morgue, where she is greeted by a nurse who says, "Room for one more, honey."

Of course, it's only a dream, right? But as any "Twilight Zone" fan will tell you, premonitions are meant to be heeded.

Gig Young gave a terrific performance as Martin Sloan, a 36-year-old ad man tired of his life, who finds himself transported to the hometown of his boyhood. There he not only basks in the remembered pleasures of carousel rides and chocolate sodas with three scoops, but also encounters himself as a child - and his parents, who understandably question his sanity.

Among the runners-up for our Top 10: "The Odyssey of Flight 33" (left), in which an airliner travels back in time; "Long-Distance Call," in which a child communicates with his dead grandmother via a toy telephone; and "Living Doll," in which the lifelike Talky Tina says, "I'm going to kill you."

Also: "Where Is Everybody?" the series' pilot, in which Earl Holliman is an Air Force pilot who discovers everyone in the world has vanished; "The After Hours," in which a woman discovers strange doings on a department store floor that doesn't really exist; and "In Praise of Pip," starring Jack Klugman as a man who revisits an amusement park with his young boy, now grown and wounded in Vietnam.
