The film is still in the midst of its official release day, but it's already shattered the record for most money made during Thursday night preview shows. The flick took in a whopping $60 million on Thursday night alone, beating the previous record holder -- 2015's Star Wars: The Force Awakens -- by $3 million.
Additionally, the latest Avengers film has been soaring overseas since its Wednesday release, raking in more than $305 million. Those international earnings, coupled with the record-breaking preview amount, gives Avengers: End Game a $365 million pre-weekend total.
The Marvel film is on course to make nearly $1 billion globally and $270 to $300 million domestically in its opening weekend. A previous film in the franchise, 2018's Avengers: Infinity War, currently holds both of those records, earning $640.5 million globally and $257.6 million domestically.

"I got a script, but it was a dummy," he told ET's Kevin Frazier at the Avengers: Endgame premiere. "There were scenes in there that I thought we were shooting that nobody ever shot."
Anthony and Joe Russo, the directors of the film, told ET that guarding the scripts from the cast was actually "a favor" to them.
"It's like doing them a favor, because it's hard to keep secrets, it's hard to keep your mouth closed," Anthony said. "We spend all day, every day, doing this for, like, the past couple years. So it's hard not to talk about what you spend all your time doing. It's a little bit of a mercy we give them by not giving them too much information."
