Moviegoing audiences in North America are not rushing back to the theater just yet. 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. Although it is enough to top the charts, it also isn’t enough to jumpstart the struggling domestic exhibition industry. 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. Other still-closed markets include North Carolina, Michigan, New Mexico and the cities of Seattle and Portland.
