Even with some mighty competition from new Matrix and Sing movies and rising concerns over the omicron variant, “Spider-Man: No Way Home” stayed in the No. 1 spot, with $81.5 million according to studio estimates Sunday. It also became 2021’s top-grossing film and crossed the $1 billion mark globally in just 12 days. Universal’s “Sing 2” came in second place with an estimated $23.8 million, while “The Matrix Resurrections” grossed $12 million to take third place. The Kurt Warner biopic “American Underdog” opened on Christmas and made an estimated $6.2 million in its first two days.
