Every year, fans come together on May 11 to celebrate National Twilight Zone Day. And if there was ever a TV show that deserved its own holiday, The Twilight Zone is definitely it. Rod Serling’s groundbreaking anthology series covered many genres—from sci-fi to horror to social commentary—but all of its episodes are united by a general sense of uneasiness. One of The Twilight Zone’s greatest strengths was its ability to pack so much story into each episode’s half-hour runtime, so it’s not too surprising that over 60 years later, many episodes are remembered for how genuinely scary they are. 

In addition to its superb writing, The Twilight Zone is also famous for the number of shocking twist endings its episodes have. Some of those twist episodes are on this list, but we’ve focused more on episodes that keep the scares going throughout. So this National Twilight Zone Day, enjoy the show’s 11 scariest episodes.

“Nightmare at 20,000 Feet”

Season 5, Episode 3

“Nightmare at 20,000 Feet” is easily the most famous Twilight Zone episode, and for good reason. Six months after suffering a nervous breakdown, Robert Wilson (William Shatner) is on a flight home to settle back into his normal life. When he glances out the window, he’s shocked to see a gremlin on the wing of the plane. He’s quick to realize that no one will believe him, since his last breakdown was also on a plane, but he continues to call people over for help when he sees the creature tampering with one of the engines. 

At first glance, “Nightmare at 20,000 Feet” wouldn't seem that scary to modern audiences, especially because the gremlin costume is very campy. But the real scares come from Robert’s palpable fear. We don’t recommend watching this one if you have a flight coming up. 

“Living Doll”

Season 5, Episode 6

When Christine is given “Talky Tina”, a wind-up doll, by her mother, Erich is instantly irritated by it. It turns out the feeling is mutual when Tina starts talking to Erich without being wound up, telling him how much she dislikes him.

Terrified, Erich tries to get rid of Tina, but no matter what he does, the doll ends up back in the house. As his paranoia begins to tear his family apart, Tina makes it clear she will not stop until Erich pays the price for his actions.
