If you are running a movie website, one of the articles you might consider writing may be about the box office performance of a particular film or a box office report itself (Example: Box Office: March 26-28, 2010). If either is the case, you should consider visiting Box Office Mojo first. Box Office Mojo should be your first stop if you need accurate box office information for domestic and international films. Box Office Mojo has daily information on all domestic in-theater films as well as films from other regions of the world.
The international section covers the weekly box office of 50 territories and includes historical box office information from three more as well as providing information for box office results for individual movies from up to 107 territories.
Box Office Mojo has historical data so you can compare a particular film you may be researching or writing about to another film.
They have information on the total financial revenue for a film (and its production budget) and you can see which is the highest grossing film in a particular category (there are many). The site also has written articles on the weekend box performance of films published every Monday.
The site also creates an overall weekend chart, combining all box office returns from around the world, excluding the United States and Canada. The overall weekend chart currently tracks the Top 40 films as well as about fifty additional films with no ranking.
A tip: weekend box office results are usually up by 5pm Sunday afternoon on Box Office Mojo.
