Summary
In the desert country around the frontier town of Flagstone, a nameless gunman known only as Harmonica (Charles Bronson) arrives looking for Frank (Henry Fonda), a killer in the pay of a dying railroad magnate. The same day, Jill McBain (Claudia Cardinale), a former New Orleans prostitute, reaches the farm of the husband she married in secret, only to find him and his children shot dead on land whose water makes it worth a fortune to whoever controls the coming railroad. Suspicion falls on the outlaw Cheyenne (Jason Robards), while Frank's employer manoeuvres to take the property out of Jill's hands. Sergio Leone's widescreen Western, scored by Ennio Morricone, unfolds as a slow, ritualised collision between the four of them.

How the score was built
We compare the reviewers of this title against every other title those same people reviewed. Each review is scored relative to the reviewer's own baseline — a 7/10 from a hard grader sits well above their average, while a 7/10 from a generous grader sits below theirs. Every reviewer then counts the same, so the result is a calibrated consensus rather than a raw average.
- Global percentile
- Where Once Upon a Time in the West lands against every title we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — titles of the same format released in the same decade. A 1970s film is judged against 1970s films, not against last year's streaming series. Ranked against Films · 1960s (1,929 titles).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each title keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 686.
