6 box-office records that 'Avengers: Endgame' has already broken on its quest to become the biggest movie of all time

AMC Theatres, the biggest theater chain in the world, announced last month that not only had "Endgame" broken its pre-sale record, but that it would open some of its theaters for three straight days to accommodate the high demand.

17 AMC Theatres stayed open round the clock Thursday night through Sunday during the movie's opening weekend last month. 29 were open non-stop from Thursday to Friday, and 18 were open Thursday through Saturday.

"Endgame" opened two days earlier in China than in the US, and had the country's biggest opening day ever (it didn't have the biggest opening weekend, though).

"Endgame" grossed $107.2 million in its opening day, and is the biggest Hollywood movie in China of all time. It's already made $575 million there. "Avengers: Infinity War" made $359 million in China during its entire run.

But it's unlikely to surpass the biggest movie ever in China, "Wolf Warrior 2," which made $854 million.

"Endgame" shattered the opening-weekend record in the US with $356 million, which was more than even Disney's initial estimate of $350 million.

It also broke the record for the biggest box office in Thursday previews with $60 million and biggest domestic opening day ever for $157 million. It beat "Star Wars: The Force Awakens" in all of these.

"Endgame" opened worldwide with $1.2 billion, the first movie to ever hit $1 billion globally in its first weekend in theaters. It's also the fastest movie to reach $1 billion, in just five days.

"Endgame" hit $2 billion globally in just 11 days, the fastest movie to ever do so. Can it hit $3 billion? If it does, it will be the only movie to ever do so (before inflation).
