The box office conversation around Supergirl has gone from disappointing to downright grim. The Milly Alcock-led new DC movie opened soft, and its second weekend did not bring the kind of hold that might have calmed down the “is this a bomb?” discourse. If anything, the numbers made the conversation louder. Let’s break down how the second weekend drop compares to other superhero flicks.
Early weekend estimates put Supergirl’s second-weekend drop around 73% to 74%, which was already bad enough. AP reported the film made just under $10 million in weekend two, calling it a steep 74% drop from its opening. Current Box Office Mojo daily totals are even rougher: $3.6 million on Friday, $2.5 million on Saturday, and about $2.5 million on Sunday. Against its $37.1 million opening weekend, that adds up to roughly $8.6 million for weekend two, or about a 76.8% drop.
That is not just a bad fall. That is comic book movie danger-zone stuff. A r/boxoffice post that tracked 190 comic book movies by second-weekend drop gives the whole thing some useful context. The post was originally built around Joker: Folie à Deux and its 81.4% second-weekend collapse, but the table is a handy measuring stick for where Supergirl now sits.
In that analysis, only 10 comic book movies had dropped 70% or more in their second weekends. That group included Dylan Dog: Dead of Night at 87.4%, Joker: Folie à Deux at 81.4%, The Marvels at 78.1%, Steel at 78%, Morbius at 73.8%, The Flash at 72.5%, Dark Phoenix at 71.5% and The Suicide Squad at 71.5%.
So where does Supergirl land? If you use the earlier 73%-74% estimate, it basically ends up in the same neighborhood as Morbius and The Flash. That alone is not where a major new superhero release wants to be. Those titles became shorthand for very different kinds of comicbook fan disappointment: one was memed back into theaters only to bomb a second time, and the other arrived with massive expectations, legacy Batman nostalgia and a marketing push that could be seen from space.
If you use the current Box Office Mojo math, though, it's even worse for Supergirl than it initially looked. A drop around 76.8% would put it just below The Marvels and Steel, and just above Morbius. That is a brutal cluster. It means Supergirl would not merely be somewhere on the comic-book box-office flop chart. It would be near the top.
Now, second-weekend drops are not always a perfect indicator of quality. The Suicide Squad is on that 70%-plus list, and plenty of people love that movie. Hellboy II: The Golden Army dropped 70.7%, and that film has a strong fan base, too. Sometimes, release timing, streaming availability, competition or front-loaded fan interest can make a movie look worse in weekend two than audience feeling alone might suggest.
But with Supergirl, the drop matters because the opening was already below expectations. A huge debut followed by a big fall is one thing. Spider-Man: No Way Home dropped 67.5% in its second weekend, but it opened to more than $260 million. Nobody was crying into their web shooters over that. When a movie opens at $37.1 million and then falls off a cliff, the math gets pretty ugly, fast.
That is the hard part for DC. Milly Alcock has had defenders, including original big-screen Supergirl star Helen Slater, and some viewers clearly connected with her version of Kara. But the box office is telling a different story. The die-hards showed up. The casual crowd did not appear to follow in meaningful numbers.
So, whether you use the 74% estimate or the roughly 76.8% final drop, the takeaway is the same: Supergirl is now flying alongside some of the roughest comic book movie second weekends ever recorded. That is not the company Kara wanted, and in my estimation, it is not the company Alcock deserves either.
Anyone who wants to make up their own mind can still catch Supergirl in theaters as part of the 2026 movie calendar. Other DC movies are also available to stream with an HBO Max subscription.
