The news keeps getting better for Marvel Studios and Disney.
On Sunday, Disney's estimates put the domestic debut of The Avengers at $200.3 million -- the biggest three-day opening of all time at the domestic box office.
But thanks to a better-than-expected Sunday, the Joss Whedon-directed tentpole came in even higher with a projected $207.1 million (the number won't be final until midday on Monday).
The 3D event pic, marking a major victory for Disney and Marvel, easily dethroned Harry Potter and the Deathly Hallows Part 2, which opened to $169.2 million last summer, then the largest debut in history.
Avengers opened a week ago overseas, earning a whopping $441.5 million through Sunday.
The pic's estimated worldwide total of $648 million already has surpassed the lifetime totals of Captain America: The First Avenger ($364 million), Thor ($449 million), Iron Man ($585 million) and Iron Man 2 ($624 million).
Avengers -- which assembles Marvel superhero characters Iron Man (Robert Downey Jr.), Thor (Chris Hemsworth), the Hulk (Mark Ruffalo), Captain America (Chris Evans), Black Widow (Scarlett Johansson), Nick Fury (Samuel L. Jackson) and Hawkeye (Jeremy Renner) -- earned a glowing A+ CinemaScore.
Avengers is now positioned to reach $1 billion in global grosses in a much-needed win for Disney, which posted a $200 million loss after John Carter cratered at the box office this year. It's also a validation of Marvel's strategy to build a franchise by turning out single titles -- Iron Man, its sequel, Thor and Captain America -- and then bring the characters together. Avengers also could reboot the Hulk film franchise.
Among other records, Avengers is the first film to cross $200 million in only three days of play at the domestic box office. It also scored the biggest Saturday gross of all time, earning $69.7 million.
