“The Odyssey” continued to exert a mighty hold on moviegoers in its second weekend in North American theaters, with $87 million in ticket sales, according to studio estimates Sunday. It’s also filmmaker Christopher Nolan’s best second weekend ever, not accounting for inflation. With $128.3 million from international theaters, “The Odyssey” has made an estimated $639.6 million globally. Regardless, the second weekend earnings are rare for a movie that opened with more than $100 million. Before the pandemic, the summer movie season would regularly exceed $4 billion.
