The results provided a boost to movie theaters, which have struggled to return to pre-pandemic levels of ticket sales. The domestic total ranked as the No. 13 movie debut of all time.

"One of the top 15 openings of all time tells me the box office is pretty healthy when there is something audiences what to see," said Jeff Bock, senior media analyst at Exhibitor Relations Co. "Marvel time and time again offers something audiences want to see."

The original "Black Panther," starring Chadwick Boseman as King T'Challa, broke ground as the first superhero movie with a predominantly Black cast.

The film took in USD 1.3 billion at worldwide box offices over its run and became the only superhero movie ever nominated for best picture at the Academy Awards.

Marvel had to rework "Wakanda Forever" after Boseman died of cancer in 2020 just before filming was supposed to begin.

The studio decided not to cast another actor in the role of T'Challa.

Instead, writer and director Ryan Coogler crafted a new film that centers around T'Challa's younger sister Shuri (Letitia Wright), his mother Queen Ramonda (Angela Bassett) and other women who step up to help lead the grieving nation.

Film critics praised the sequel, saying Marvel had succeeded in paying tribute to Boseman while offering a compelling film despite the loss of the popular lead character.

The movie scored an 84% positive rating from movie critics, and 95 per cent positive from audiences, in reviews collected on the Rotten Tomatoes website.

Bock said his local theater was buzzing with a packed crowd for one of the first "Wakanda Forever" screenings. "I hadn't seen that for months," he said.

Box office year-to-date ticket sales stand at USD 6.5 billion through Sunday in the domestic market, according to Comscore. That is 33 per cent below the pre-pandemic year of 2019.

The problem is a thin slate of films, Bock said. Many Hollywood studios are still dealing with COVID-induced production delays. The number of wide releases in 2022 is 37 per cent lower than in 2017.

Theaters are looking ahead to Disney's "Avatar: The Way of Water" in December, and a larger number of films in 2023, to increase ticket sales.
