Official answer
65
movies
How to estimate it
Fermi’s official “Napkin math”
Titanic was the first movie to make a billion dollars, back in the late 90s, so call it 30 years. How many films clear that bar in a year? Maybe 2 or 3 in a good year now, fewer early on, so call it 2.
- Years since Titanic
- ≈ 30
- Billion-dollar movies a year
- × 2
- 30 × 2
- ≈ 60
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Films at $1 billion or more worldwide, released before 2026
- 60
- 2026 releases that have crossed so far (The Super Mario Galaxy Movie, Michael, Toy Story 5, Spider-Man: Brand New Day, The Odyssey)
- + 5
- Total on Box Office Mojo's all-time worldwide chart
- = 65
