Since 2008’s “Iron Man,” the Marvel machine has been one of the most unstoppable forces in box-office history. Now, though, that aura of invincibility is showing signs of wear and tear.

The superhero factory hit a new low with the weekend launch of “The Marvels,” which opened with just $47 million, according to studio estimates Sunday.

The 33rd installment in the Marvel Cinematic Universe, a sequel to the 2019 Brie Larson-led “Captain Marvel,” managed less than a third of the $153.4 million its predecessor launched with before ultimately taking in $1.13 billion worldwide.

Sequels, especially in Marvel Land, aren’t supposed to fall off a cliff. Yet “The Marvels” debuted with more than $100 million less than “Captain Marvel” opened with — something no sequel before has ever done. David A. Gross, who runs the movie consulting firm Franchise Research Entertainment, called it “an unprecedented Marvel box-office collapse.”

The previous low for a Walt Disney Co.-owned Marvel movie was “Ant-Man,” which bowed with $57.2 million in 2015. Otherwise, you have to go outside the Disney MCU to find such a slow start for a Marvel movie — releases like Universal’s “The Incredible Hulk” with $55.4 million in 2008, Sony’s “Morbius” with $39 million in 2022 or 20th Century Fox’s “Fantastic Four” reboot with $25.6 million in 2015.

But “The Marvels” was a $200 million-plus sequel to a billion-dollar blockbuster. It was also an exceptional Marvel release in numerous ways. The film, directed by Nia DaCosta, was the first MCU release directed by a Black woman. It was also the rare Marvel movie led by three women — Larson, Teyonah Parris and Iman Vellani.

Reviews weren’t strong (62% fresh on Rotten Tomatoes) and neither was audience reaction. “The Marvels” is only the third MCU release to receive a “B” CinemaScore from moviegoers, following “Eternals” and “Ant-Man and the Wasp: Quantamania.”

“The Marvels,” which added $63.3 million in overseas ticket sales, may go down as a turning point in the MCU. Over the years, the franchise has collected $33 billion globally — a point Disney noted in reporting its grosses Sunday.
