Box-Office Top 100 Films of All-Time: Rankings of both US (Domestic) and Worldwide Box-Office blockbusters have been compiled from various recent sources. The domestic rankings, divided into unadjusted and adjusted for inflation,* are based upon theatrical box office receipts (including some theatrical re-release receipts) and do not include video rentals, TV rights, international box office figures, or other revenues. A few other sites post all-time box-office information, including the Internet Movie DataBase, Boxoffice.com, Boxofficemojo.com, and The-numbers.com.

The 100 Greatest Films that have been selected at this site are identified throughout by a yellow star .

The Three Lists:

• The Domestic, Unadjusted (for inflation) list of box-office champs is top heavy with recent films. Rankings may change daily with every new blockbuster release. There are few films that are classics or films from Hollywood's Golden Era in this list. Top-grossing, financially-successful films often rate lower in artistic achievement. Blockbusters, special effects wonders, films with sequels and expensive campaign and publicity ads fill many of the positions. (Notice that there are very few pre-2000 films in the unadjusted list.)
• The Domestic, Adjusted (for inflation) list of box-office champs - with rankings that don't vary much from month to month (and therefore is not updated as regularly) - takes into account inflationary factors such as ticket prices and any re-issues or re-releases, and is more reflective of a film's actual appeal. [It is inflation-adjusted to the 2020 average ticket price of $9.37. Most pre-1980 pictures achieved their totals through multiple releases.] The escalating price of theatre tickets would otherwise bias a list of all-time blockbuster films to recent releases. See more details.
• The Worldwide list of box-office-champs - in some cases, the gross earnings were made with multiple releases. Currently, less than a tenth of the films were not in the decade of the 2000s or thereafter.
