To add a few more records to the list, Disney noted that Endgame was the biggest IMAX global debut with $91.5 million. It’s also the 8th Marvel Studios film to cross $1 billion, and the second to do so this year after Captain Marvel. At the moment, Endgame is the 18th largest worldwide release, but that number is sure to change in the coming weeks. According to Box Office Mojo, the blockbuster sequel could make as much as $920 million domestically if it follows the pattern of Infinity War, but tracking is apparently unclear at the moment.
