100 Top Grossing Movies Of All Time

Methodology

To determine the top 100 grossing movies of all time, 24/7 Tempo reviewed the lifetime domestic gross of 17,575 films produced between 1977 and 2020 from movie data site Box Office Mojo, which collects box office gross sales data.

Production budgets and number of tickets sold also came from Box Office Mojo. Actors and roles information was obtained from the International Movie Database (IMDb).

We adjusted each domestic box office gross for inflation using the annual Personal Consumption Expenditure Price-Index (PCEPI) from the economic research library of the U.S. Federal Reserve. Domestic gross includes both the U.S. and Canada.
