“Joker: Folie à Deux” continues its downward trend after its opening weekend flop, posting historically low box office numbers in its second week.

The sequel to the 2019 film “Joker,” which was a hit with both critics and fans, “Joker: Folie à Deux” grossed $38 million at the U.S. box office in its opening weekend, well underperforming previous forecasts in the range of $50 million to $70 million.

But the second weekend was even worse, grossing just $7 million from 4,102 theaters in the United States. The 81% decline is the largest decline in comic book film history and one of the largest domestic declines for a film.

With an 81% decline, “Joker: Folie à Deux” ranks among the 20 biggest second weekend declines of all time, according to charts from Box Office Mojo, which measures box office data collected since 1982.

The record decline for a comic book film was previously seen by “The Marvels,” which was a box office hit last year and suffered a 78% second-weekend drop after opening in 4,030 theaters.

“Joker: Folie à Deux” has grossed $165 million worldwide so far and is far from covering its $200 million budget.

In comparison, Joker was made on a third of the sequel's budget and opened to $96.2 million in the U.S., bringing it to $248.4 million worldwide in just one weekend. In total, it grossed more than $1 billion worldwide, making it the first R-rated film to do so. It remained the highest-grossing R-rated film until this year, when it was surpassed by another comic book film, Deadpool & Wolverine.

“Joker” was also a critical success, winning two Oscars from eleven nominations, including Best Actor for Joaquin Phoenix in the title role.

Phoenix reprises his role in the episode, while Lady Gaga joins the cast as love interest Lee Quinzel, based on the character Harley Quinn.

The sequel, which is a musical, was widely dismissed by critics as “dull” and “frighteningly boring.”

Both the Guardian and the Observer praised Lady Gaga's performance in their three-star reviews, but called the film “laborious” and “indulgent.”
