On the cusp of the studio’s merger with Paramount, Warner Bros.’ “Digger” flopped in its opening weekend, handing Tom Cruise one of the worst debuts of his career and serving as a bitter final note for Warner Bros. as a stand-alone studio.

No. 1 in North American theaters instead went to Amazon MGM’s “Verity,” extending the streak for Colleen Hoover adaptations at the box office. It debuted with $32.6 million. The film, directed by Michael Showalter, stars Dakota Johnson as a writer hired to ghostwrite a book series by an incapacitated author (Anne Hathaway).

But all eyes were on how “Digger,” one of the year’s biggest gambles, would perform. Alejandro G. Iñárritu’s critically panned satire grossed a paltry $8 million domestically. Cruise is typically a big draw overseas, but international sales, $12 million from 74 markets, were also weak.

It’s a painfully rough start for a movie that cost at least $125 million to make. Reports have pegged the production budget closer to $150 million. The marketing spend is estimated at another $100 million.

“Digger” had been positioned as a potential awards-season heavyweight, dated almost exactly the same as Warner Bros.’ “One Battle After Another” was last year. “Digger” is a similarly politically charged release that handed a large budget to a top filmmaker working from an original story.

But this big swing by Warner Bros. Motion Picture Group co-chairs Michael De Luca and Pamela Abdy won’t pay off as well as “One Battle After Another,” which grossed $213.2 million worldwide and, more importantly, won best picture at the Academy Awards.

The disappointing opening comes just as Paramount Skydance is closing its acquisition of Warner Bros. Discovery. In a flush year for Hollywood, Warner Bros. has failed to get one film to $100 million domestically, though its December release, “Dune: Part III,” will easily cross that.

“‘Digger’ collapsed (last) weekend and the new management of the combined Paramount and Warner Bros., David Ellison and Josh Greenstein and Dana Goldberg, will soon decide what kind of movies they want from WB,” wrote David A. Gross, a film consultant who publishes a newsletter on box-office figures. “Paramount does not have a recent history of making big, auteur-driven films like this — that strategy appears to be over and out.”

Critics (51% fresh on Rotten Tomatoes) slammed “Digger” as a strained climate change farce, though Cruise’s over-the-top performance was received more warmly. Audiences agreed, giving it a “C+” CinemaScore.

Cruise has spent most of the past decade starring in “Mission: Impossible” movies and “Top Gun: Maverick,” both franchises that have allowed him to remain a top action hero into his 60s. The 64-year-old’s last major box-office disappointment was 2017’s “The Mummy,” which grossed $409.2 million worldwide on a $195 million budget.

To help sell “Digger,” Cruise pulled out all the stops. He even granted his first lengthy magazine interview in years.

The previous weekend’s top film, “Avengers: Endgame: Encore,” slid to seventh place with $4.4 million domestically and $14.4 million overseas. But the Marvel rerelease’s second week allowed “Endgame” to just nudge ahead of “Avatar” to reclaim the title of highest grossing film ever, not accounting for inflation. The two films have traded spots in recent years with rereleases. “Endgame” now tallies $2.9255 billion, while “Avatar” has $2.9237 billion.

The rest of the top-sellers in cinemas over the weekend were holdovers: Zach Cregger’s video game adaptation “Resident Evil” for Sony Pictures; Lance Oppenheim’s A24 drama “Primetime,” with Robert Pattinson as “To Catch a Predator” host Chris Hansen; and Paramount’s “Heart of the Beast,” starring Brad Pitt as a retired veteran who treks through the Alaskan wilderness with his combat dog after a plane crash.

In its third week, “Resident Evil” came in second with $12.5 million. “Heart of the Beast” followed with $11 million. And “Primetime” collected $8 million in its second weekend.

1. “Verity,” $32.6 million

2. “Resident Evil,” $12.5 million

3. “Heart of the Beast,” $11 million
