About This Dataset
Highest-Grossing Documentary Films of All Time
Documentary films ranked by total worldwide box office gross, measured in millions of USD. Fahrenheit 9/11 (2004) by Michael Moore remains the highest-grossing documentary in cinema history with $222 million worldwide — a theatrical achievement that demonstrated the commercial viability of politically engaged documentary filmmaking and opened the door for a generation of high-budget documentaries that audiences would pay to see in cinemas rather than simply watch on television.
Analysis
The top three in Worldwide Box Office (Million USD) in 2018 are Fahrenheit 9/11 (2004) (222), March of the Penguins (2005) (127) and Earth (2007) (109). The 8 entries cover a range of 193, from 222 down to 29. First and second are separated by 95, so the leader sits inside the field rather than apart from it. Only 2 of the 8 reach even half the leader's figure (111 or more).

How the figures are calculated
- Values use the measure and unit named on this page. Consult the dataset description and cited source for coverage, definitions and any unit conversions. Displayed values may be rounded for readability.
- Missing years are left empty rather than estimated — no interpolation, no carrying a previous year forward.
- Change is measured between the first and last year in which an entity actually reported a value, so a series that starts late is not penalised for the years before it existed.
- The compound annual rate is (last ÷ first)^(1 ÷ years) − 1, using those same two reported years.
- Entities are ranked highest-first on their value in 2018.
- An entity that reported nothing in the latest year is still listed — it follows the ranked entities in the table rather than being dropped.
