There are few movies coming out this year that are guaranteed to print money as quickly as Avengers: Endgame. The fourth and, presumably, the final film in Marvel’s core unifying series—or this phase of it, anyway—is hitting theaters this Friday, bringing one chapter of a mammoth superhero saga to a close. (How future solo films like the potential Black Widow spin-off will be handled remains to be seen.) The question now, though, isn’t whether Avengers: Endgame will be a billion-dollar movie, but rather just how quickly it will become a billion-dollar movie—and whether it will best Avengers: Infinity War, which made a shocking $2 billion worldwide.

Let’s start with tracking. According to the early estimations, Endgame could earn a whopping $270 million to $300 million in its opening weekend in North America, courtesy of its massive, 4,600 theater-wide release, per The Hollywood Reporter. Globally, it could launch with $850 to $900 million. With those kind of early figures, the film could easily earn $1 billion in less than a week, a record for an Avengers movie. By comparison, Infinity War crossed the $1 billion mark in a week and a half.

However, Endgame also has an Achilles’ heel—its running time is a touch over three hours, which limits the amount of times it can be shown each day in theaters. Per T.H.R., Disney is combatting that weakness by adding a record number of around-the-clock screenings; more than a dozen of AMC locations, for example, will stay open constantly throughout the opening weekend, without taking breaks between late-night and early-morning screenings. (Thank the ushers and concessions people at your local theater, folks.)

The good omens are already out for Endgame, though. The film opened in China on Wednesday, picking up a record $107.2 million on its first day of release, a sum that includes a record $28.2 million in midnight previews. Per T.H.R., Endgame accounted for 99 percent of all movie tickets sold on Wednesday in China. Local tracking places the film at around $521 million when all is said and done, which will catapult the film to historic global sales. By comparison, Infinity War earned $359 million in China.

Per this tracking, Endgame seems poised to set quite a few records in its opening weekend, including the best April opening weekend, the biggest Thursday preview gross, and becoming the fastest film to hit $300 million, sparring with records previously set by Infinity War and Star Wars: The Force Awakens.
