What Christopher Nolan achieved in summer 2023 with Oppenheimer was revolutionary. Not only was the Cillian Murphy-starrer an original film outside any franchise lore, but one that pleased fans, critics, and the Academy while bringing the director a paycheck north of $100 million. Oppenheimer also had the company of Barbie, a comedy featuring Margot Robbie and Ryan Gosling, which rode Oppenheimer’s coattails to unprecedented success.
This led to a double-feature phenomenon colloquially dubbed Barbenheimer, where Nolan’s fans didn’t shy away from giving Barbie’s female-centric, pink allure a try, reviving Hollywood in the process. But did you know this wasn’t the first major clash of its kind spearheaded by the Inception filmmaker
The Dark Knight And Mamma Mia Were Released On The Same Day
What made Barbenheimer a tremendous success was the arrival of two tentpoles on the same day, each appealing to contrasting viewers — those wanting intellect, history, and physics interlaced in Oppenheimer, and those looking to have a fun time while cosplaying to participate in Barbie. While the former was an hour longer, an R-rated political drama, and far too byzantine for the target audiences of the latter, it nevertheless made over $976 million at the worldwide box office, sharing screens with Barbie, which made $1.44 billion (according to Box Office Mojo).
However, an indifferent event had occurred precisely 15 years prior to the same week, and once again, it was Christopher Nolan. This time, his The Dark Knight flew in theaters the same day as the female-focused musical comedy Mamma Mia! Both these movies were produced by Warner Bros. and Universal—the same powerhouses behind Barbenheimer—but more significantly, they both became huge blockbusters.
In other words, Nolan had long set an example of bipartisanship in Hollywood, and both instances reflected an eclectic atmosphere, spanning genders and genres, rendering events extravagant rather than a monotonous trip to the cinema.
The Dark Knight & Mamma Mia! Were Bigger Hits Than Oppenheimer & Barbie
Back in 2008, the billion-dollar mark was almost elusive, and neither superhero movies nor musicals had dared enter the charts of the highest-grossing films. But The Dark Knight and Mamma Mia! (“Dark Mamma”?) did not let those convictions precede their reputations. In conclusion, both the Heath Ledger–Christian Bale film and the Phyllida Lloyd directorial became the highest-grossing films in their genre.
Domestically, the Batman flick reigned supreme with $535 million, while internationally, both The Dark Knight and the Meryl Streep–starrer made nearly the same amount: $470 million. The latter was re-released in the United Kingdom in 2025 and doubled its tally in the market from $95 million to $186 million, outpacing its North American numbers ($144 million).
According to Box Office Mojo, The Dark Knight emerged as the second billion-dollar feature at $1.01 billion, while Mamma Mia’s global box office collection also reached an impressive $703 million, as per the same source.
The enormity of these accomplishments becomes crystal clear when accounting for their combined gross of $1.7 billion, unadjusted for inflation—which isn’t far from the $2.4 billion Barbenheimer would make 15 years later. Not to mention, the 2008 double feature has a stronger legacy status than the 2023 pair.
Box Office Summary
The Dark Knight Total Domestic Gross $534.98 million
The Dark Knight Total Worldwide Gross $1.012 billion
