List of highest-grossing openings for films

The following is a list of the highest-grossing opening weekends for films. The list is dominated by recent films due to steadily increasing production and marketing budgets, and modern films opening on more screens. Another contributing factor is inflation not being taken into account.

Biggest worldwide openings on record
This list charts films that had openings in excess of $250 million worldwide. Since films do not open on Fridays in many markets, the 'opening' is taken to be the gross between the first day of release and the first Sunday following the movie's release. Figures prior to the year 2002 are not available.

This list does not take into account country-by-country variations in release dates. Therefore, in some cases opening weekend grosses from many, or even most countries may not be included. All figures are not adjusted for inflation and therefore a direct comparison of the films from different years cannot be made.
