The interval between summer and holiday movie seasons can sometimes produce unexpected successes at the box office. During this timeframe, there are usually fewer big-budget studio releases competing over Fourth of July and Christmas, which opens up opportunities for lesser-known productions to make a significant impact. This September has already witnessed the horror sequel “The Conjuring: Last Rites” capitalize on limited competition by achieving a record-breaking opening weekend. Now, another new production has managed to secure a place in cinematic history. The anime film “Demon Slayer: Infinity Castle” launched in U.S. theaters this weekend, and it’s off to an extraordinary start.
Based on Deadline’s report, Demon Slayer: Infinity Castle made approximately $33 million domestically on September 12th. If this trend continues, it is predicted to gross between $56-60 million by the end of this weekend. This potential earnings would make it the biggest opening for a Sony film in 2020 so far, surpassing the previous record set by 28 Years Later at $30 million. The film’s performance on Friday suggests that there is a possibility it could even earn up to $70 million over its first three days.
How Demon Slayer: Infinity Castle Dominated the Box Office This Weekend

At an opportune moment, Demon Slayer: Infinity Castle graced the big screen when the Hollywood release schedule was less crowded. After Weapons premiered in early August and surpassed predictions, only The Conjuring: Last Rites made a noticeable impact at the box office during this period. Over Labor Day weekend, newcomers Caught Stealing and The Roses were eclipsed by the 50th anniversary rerelease of Jaws, demonstrating a lack of interest in the latest offerings. Even the critically praised Stephen King adaptation, The Long Walk, which debuted with Demon Slayer, is only predicted to earn $11-13.5 million domestically.
Besides a strong fan base due to its immense popularity, Demon Slayer climbed high in the box office rankings not just because of less competition, but also because of its captivating appeal. Similarly, Infinity Castle benefited from being adapted from one of the best-selling manga series ever, ensuring a large and global audience eager for the big screen adaptation. Moreover, it received rave reviews with a 97% approval rating on Rotten Tomatoes, which made audiences feel confident about watching it in theaters, significantly increasing its box office potential.
As a devoted fan, I must say it’s quite gratifying to witness the triumph of “Demon Slayers: Infinity Castle.” After Sony parted ways with “Kpop Demon Hunters,” selling it to Netflix for a whopping $20 million, this turn of events feels like a breath of fresh air. Although “Kpop Demon Hunters” went on to become one of Netflix’s biggest films ever and had impressive box office results in its limited release, Sony might have missed out on an enormous animated blockbuster. However, the success of “Demon Slayers: Infinity Castle” makes that tough pill a bit easier to swallow, as it marks Sony’s best opening in quite some time. Furthermore, predictions suggest that “Infinity Castle” will surpass the debuts of high-profile films such as “Venom: The Last Dance.
It’s intriguing to observe whether “Demon Slayers: Infinity Castle” will maintain its success over the coming weeks. Films that experience strong initial openings often face a challenge due to being front-loaded, as their performance heavily relies on fan excitement for the movie launch. This enthusiasm can sometimes lead to steep decreases in attendance during the second week, negatively impacting future predictions. However, even if “Demon Slayers” experiences a slight dip, it might still have a chance to secure the box office top spot again next weekend. Notable upcoming releases such as the football horror movie “Him” and romantic fantasy drama “A Big Bold Beautiful Journey” are not anticipated to attract large audiences. This could potentially provide “Infinity Castle” with an opportunity to retain the No. 1 position.
