This list charts films the 50 biggest worldwide openings. 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.
