The Outer Limits (1963)

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 Duplicate Man - S2-E13

Trivia: The bird-beaked alien megasoid from this episode made a "guest appearance" in the first Star Trek pilot, shot the same year (1964). It can be glimpsed in one of the Keeper's enclosures in the uncut version of "The Cage." (00:02:00)
