In the second major weekend for U.S. and Canadian movie theaters, Christopher Nolan’s “Tenet” earned only $6.7 million from 2,910 locations, according to studio estimates Sunday. Warner Bros’ sci-fi thriller was viewed as the main litmus test for whether audiences were ready to embrace the theatrical experience again, after nearly six months of shuttered theaters due to the pandemic.

Although it was enough to top the scattershot domestic releases, it also isn’t enough to jumpstart the struggling exhibition industry. Warner Bros. has already pushed back its next major release, “Wonder Woman 1984,” even further.

The weekend’s only major new opener was Sony’s PG-13 rom-com “The Broken Hearts Gallery,” which earned an estimated $1.1 million from 2,204 North American locations. The film, from first-time writer director Natalie Krinsky and executive produced by Selena Gomez, is about a 20-something gallerist played by Geraldine Viswanathan who creates an art exhibit with souvenirs from her past relationships.

The studio is optimistic about its performance and potential.

“The early numbers are really encouraging,” said Adrian Smith, the president of president of Sony Pictures domestic distribution.

Smith noted that the film will have a slow roll out as more theaters continue to open in the U.S.

Roughly two-thirds of the domestic market is open and theaters are operating at limited capacity and with limited showtimes. Two of the country’s biggest markets, New York and Los Angeles, remain closed. Other still-closed markets include North Carolina, Michigan, New Mexico and the cities of Seattle and Portland.

Other notable domestic weekend numbers include Disney’s “The New Mutants,” which added $2.1 million from 2,704 locations in its third weekend and Solstice’s Russell Crowe pic “Unhinged,” which earned an additional $1.5 million in week four.

“Every week is a bit of a litmus test about how potential moviegoers are feeling about going to the theater,” said Paul Dergarabedian, Comscore’s senior media analyst. “I think audiences are slowly going back.”

But, he noted, “you can’t apply the norms of how we analyze or report the box office.”

Comscore has not even been able to report a traditional “Top 10” chart because of the unusual marketplace which Dergarabedian likened to a “relaunch” or a “reboot” of the movie theater.

The landscape is more encouraging internationally, where “Tenet” this weekend added over $30 million, pushing its global total to $207 million.

But new movies are not enough on their own. In China, The Walt Disney Co.’s “Mulan” had a disappointing debut of only $23.2 million. The low launch nonetheless claimed the film the No. 1 spot in the country where an estimated 91% of theaters are open but limited to 50% capacity. The studio noted that its opening is around the same level as “Cinderella” and “Maleficent: Mistress of Evil.”

Globally, “Mulan” has earned $37.6 million to date, although that number is not representative of the total earnings. The live-action epic, which has also been embroiled in controversy over its filming location, is not playing in North American theaters. Instead, it is available for a $29.99 rental on the company’s Disney+ service. The streaming earnings were not made available.

But pre-COVID metrics of success and failure are difficult to apply, especially to the first films out of the gates. And, according to Dergarabedian, it might be that way for a while.

“We are not in a traditional marketplace and we are not in a traditional mode of analyses,” Dergarabedian said. “It’s going to take some time to properly assess the long-term impact of the pandemic.”
