Capricorn One
A determined reporter uncovers a government conspiracy when he learns the first Mars landing was faked, forcing three astronauts to fight for their lives and the truth as NASA and its allies move to silence them.
Synopsis
In order to protect the reputation of the American space program, a team of NASA administrators turn the first Mars mission into a phony Mars landing. Under threat of harm to their families the astronauts play their part in the deception on a staged set in a deserted military base. But once the real ship returns to Earth and burns up on re-entry, the astronauts become liabilities. Now, with the help of a crusading reporter, they must battle a sinister conspiracy that will stop at nothing to keep the truth hidden.

How many hands made this film
The scale of the collaboration
Principal cast & crew: 28
These are the principals we have on file — the full crew ran to the hundreds. Every film this size was made by far more hands than any credits list ever names.
Why a floor?
This is a minimum, not a total. We only count the credits we’ve captured so far, and coverage is uneven — a blockbuster might show a few hundred names while another of the same size shows a couple dozen. The real crews all ran into the thousands. The number here only grows as full credits are enriched — so we frame it as a floor, never a headcount.
Box Office
Box office
⚖️ Fell short of break-even — grossed 2.4× its budget
Why 2.5×?
Cinemas keep roughly half of every ticket sold, and a wide release’s marketing often costs about as much again as the film — so a movie needs to gross around 2.5× its production budget just to break even theatrically. It’s a rule of thumb, not the studio’s ledger (home video and streaming come later).
