Revealing mistake: Janie is frozen in place on her tricycle, but the 5-year-old actress has a hard time holding still. She's visibly fidgeting. And when a freeze-frame of her is used for close-ups, there's a black blotch on the film over her neck. (00:26:30)

1 revealing mistake in The Premonition
Behold, Eck! - S2-E3
Continuity mistake: When Dr. Stone's assistant helps him up from the floor, there's a lopsided, circular diagram drawn on the chalkboard behind them. One shot later, the diagram has changed into a perfectly round circle and has moved itself several inches higher on the board. (00:06:10)
Dr. Paul Wayne: So what difference does it make, whether it's 20 minutes or 20 years, since neither amounts to the faintest echo of the tiniest whisper in the thunder of time.
The Forms of Things Unknown - S1-E32
Trivia: This is the only Outer Limits episode that lacks both opening and closing narration. It was absent because "Forms" was the unsold pilot for a series called The Unknown. A second version, stripped of all its supernatural elements (Tone was simply a mad scientist, not a real time traveler), also failed to sell.
