Space Jam: A New Legacy has proved a slam dunk by taking $31.6m (£23.8m) in its opening weekend to top the North American box office.
A joint streaming release, it sets a pandemic-era record for a family film.
The live-action/animated basketball film – a sequel to the 1996 original starring Michael Jordan – sees NBA star LeBron James team up with the Looney Tunes characters to save his son.
Its success, despite poor reviews, means it topples Marvel's Black Widow.
The superhero adventure, starring Scarlett Johansson as Natasha Romanoff, brought in $26.3m (£18m) in its second weekend. This marked a steep 67% decline from its $80m (£58m) inaugural sales that made it the highest-grossing post-Covid cinema release.

Also made available near-simultaneously on the Disney Plus streaming service as part of the company's multi-platform release strategy to mitigate the pandemic, it collected an additional $60m (£43m) worldwide from subscribers.
Dual release strategy questioned
However, the scale of subsequent drop-off will be of concern to Marvel studio bosses given its $200m (£145m) budget and raise questions over the viability of the dual release model, despite Disney's initial positivity.
Although it is normal for a film's box office earnings to lessen considerably in its second week, particularly in the current climate, The Hollywood Reporter noted that Black Widow suffered one of the biggest drops ever for a Marvel title, and the worst among the Marvel Cinematic Universe films released by Disney. The film also still does not have a release date in China, a vital market for Hollywood.
Reacting to the collapse, a statement from the US-based National Association of Theatre Owners said it demonstrated the importance of maintaining an exclusive cinema release window. "An exclusive theatrical release means more revenue for all stakeholders in every cycle of the movie's life," it told Variety.
"The many questions raised by Disney's limited release of streaming data opening weekend are being rapidly answered by Black Widow's disappointing and anomalous performance".
The BBC has contacted Disney for comment. The streaming figures for the Warner Bros-backed Space Jam: New Legacy, have not been released by HBO Max.
The box office spat marks the latest battle in ongoing tensions between home service streaming giants and traditional cinemas hampered by pandemic closures.
The owners of the Odeon cinema chain, AMC, briefly threatened to boycott Universal's movies last year before reaching an agreement. Warner Bros, meanwhile, heightened tensions when it announced its entire 2021 film slate, including New Legacy, would premiere on HBO Max and cinemas on the same day.
