Avengers: Endgame has shattered the record for biggest opening weekend with an estimated $1.2 billion (£929bn) in ticket sales globally.
The Disney blockbuster has become the fastest film ever to break the $1 billion barrier, doing so in just five days.
The Avengers finale starring Joe Russo, Paul Rudd, Scarlett Johansson, Chris Hemsworth and Anthony Russo far exceeded even its own huge expectations, according to studio estimates.
The movie had been forecast to open between $260 and $300 million (£202-230m) in US and Canadian cinemas, but droves of moviegoers helped smash the previous record of $257.7 million (£198m), set last year by Avengers: Infinity War.
Worldwide, it obliterated the previous record of $640.5 million, also set by Infinity War.
Endgame has already made more than movies like Skyfall, Aquaman and The Dark Knight Rises grossed in their entire runs.
Alan Horn, Disney chairman, credited Marvel Studios and its president, Kevin Feige, for challenging "notions of what is possible at the movie theater".
"This weekend's monumental success is a testament to the world they've envisioned, the talent involved, and their collective passion, matched by the irrepressible enthusiasm of fans around the world," Mr Horn said.
To accommodate demand, the Walt Disney Corporation released Endgame in more cinemas - 4,662 in the US and Canada - than any opening before.
Advance ticketing services set new records and some cinemas even stayed open 72 hours straight.
"We've got some really tired staff," said John Fithian, president and chief executive of America’s National Association of Theater Owners.
"I talked to an exhibitor in Kansas who said, 'I've never sold out a 7 am show on Saturday morning before,' and they were doing it all across their circuit."
