NEW YORK In a litmus test for American moviegoing in the pandemic, Christopher Nolan's Tenet brought in an estimated $20.2 million through the holiday weekend in U.S. and Canadian theaters. Theaters in Canada, where COVID-19 cases are much lower than in the U.S., began showing Tenet a week earlier. In two weeks of release, its overseas total is $126 million, with a global tally thus far of $146.2 million. The film, which cost $200 million to make and at least $100 million to market, will need to get close to $500 million to break even. Disney's The New Mutants," a long delayed X-Men spinoff, collected about $7 million in 2,412 locations last weekend.
