Dick York previously appeared in "The Purple Testament," and later became the first Darrin Stephens on Bewitched.

The original idea for this episode came from a short story written by Ted Kneeland. Kneeland was a writer, producer, director that worked for NBC before going to Australia to start Australian broadcasting in 1953.

Cyril Delevanti returns in "The Silence," "A Piano in the House" and "Passage on the Lady Anne."

Frank London is also in "Steel."

Hayden Rorke is best known for his role in I Dream of Jeannie as Colonel Dr. Alfred E. Bellows.

The concept of this episode was later recycled in the 1985 TZ episode "20/20 Vision." The means of telepathy in that episode are a pair of cracked eyeglasses, an allusion to the fact that Hector cracks his glasses in this episode.

Opening Narration
Narrator: Mr. Hector B. Poole, resident of the Twilight Zone. Flip a coin and keep flipping it. What are the odds? Half the time it will come up heads, half the time tails. But in one freakish chance in a million, it'll land on its edge. Mr. Hector B. Poole, a bright human coin, on his way to the bank.

Hector B. Poole: Miss Turner?
Helen Turner: Yes, Mr. Poole?
Hector B. Poole: Well, uh, please don't be offended but, well, I, uh, I would like to thank you for your kind thoughts.
Helen Turner: Well, I don't think I quite understand, Mr. Poole.
Mr. Brand: Romancing the help, Mr. Poole? Well, who can blame you? Miss Turner is the prettiest girl in the accounts section. (Thinking) Which is saying absolutely nothing. I haven't seen such an aggregation of beasts since the last time I went to the circus. (Aloud) Not much chance for socializing around a bank, is there? (Thinking) This one's probably a tiger under the proper conditions. All the sweet, prim types revert to the jungle once more. (Poole pours water on his head) You did that deliberately! I'll see you later about this.
Helen Turner: (Thinking) Good for you. He certainly had it coming. (Aloud) I suppose I should get back to my desk.
L.J. Smithers: (Thinking) Four hundred and one. Four hundred and two. Four hundred and three. Twenty years at the same desk. It isn't fair. Ah, but they'll be sorry for their treatment of me. Yes, at four-thirty this afternoon, I'll go into the vault like I always do. I'll take my briefcase with me and no one will suspect a thing. I'll fill my briefcase with currency and be on ship to Bermuda by nightfall. They'll all be sorry. Yes, indeed. I wonder how long it will take them to discover that the money is gone.

Closing Narration
Narrator: One time in a million, a coin will land on its edge, but all it takes to knock it over is a vagrant breeze, a vibration or a slight blow. Hector B. Poole, a human coin, on edge for a brief time in the Twilight Zone.
