"People Are Alike All Over" is the twenty-fifth episode of the The Twilight Zone.
"You are looking at a species of flimsy little 2-legged animal with extremely small heads whose name is Man. Warren Marcusson, age 35. Samuel A. Conrad, age 31. They're taking a highway into space- Man unshackling himself and sending his tiny, groping fingers into the unknown. Their destination is Mars, and in just a moment we'll land there with them."
"Species of animal brought back alive. Interesting similarity in physical characteristics to human beings in head, trunk, arms, legs, feet. Very tiny undeveloped brain; comes from this primitive planet called Earth. Calls himself Samuel Conrad, and he will remain here in his cage with the running water and electricity and the central heat, as long as he lives. Samuel Conrad has found the Twilight Zone."

- Rod Serling changed a couple of elements from the original source story (Brothers Beyond The Void, by Paul Fairman) for this episode. In the original story the protagonist is Marcusson and Conrad is only in the beginning of the story as Marcusson makes the trip to Mars alone. Serling also changed the climatic utterance from the story's mundane "People are the same everywhere," to his more poignant version. It isn't clear why Serling changed the story and made Conrad the protagonist.
- Marcusson mentions they have traveled 35 million miles to Mars. The distance between Earth and Mars ranges between 36 million and 250 million miles due to both having slightly elliptical orbits and different lengths of time to orbit the sun.
- As in many other episodes, several props from Forbidden Planet are used, especially in the interior of the astronauts' spaceship.
