LOS ANGELES — Walt Disney Co. said "Avengers: Age of Ultron" produced $191.3 million in box-office receipts in its opening weekend in North America, more than first reported, after tallying Sunday sales.

Disney on Sunday reported $187.7 million in ticket sales in the U.S. and Canada, after forecasting at least $200 million on Friday and then saying attendance was hurt by the Mayweather- Pacquiao fight on Saturday.

The tally was enough to make the film the second-biggest U.S. opening ever, behind Disney's original "Avengers," which made $207.4 in 2012. Sales on Sunday came in higher than estimated after a slow Saturday, when the boxing match between Floyd Mayweather and Manny Pacquiao siphoned off business. The Kentucky Derby, and basketball and hockey playoffs also hurt.

"We saw business being impacted more than we normally would have," Dave Hollis, executive vice president of theatrical distribution for Walt Disney Studios, said in an interview Sunday. He called Saturday "arguably one of the greatest days in sports."

Outside the United States, "Age of Ultron" produced $439.8 million, Burbank, California-based Disney said Monday in an emailed statement. That brings the film's total to $631.1 million, the company said.

With "Age of Ultron," which features Iron Man, Captain America and other comic-book superheroes, Disney's Marvel now holds the record for the top three domestic openings, according to data from Rentrak Corp. The latest film knocked the 2013 release "Iron Man 3" to third place. That movie generated $174.1 million.

The weekend started off strong for "Age of Ultron." Disney reported $84.5 million in domestic sales on Friday, an amount that put the film on pace to make $200 million to $210 million for the weekend. The record set by "Marvel's the Avengers" was "in sight," Disney said.

The movie dropped off to $57.2 million on Saturday, according to Rentrak, below what Disney had figured in its Friday forecast. Sunday sales totaled about $49.6 million.

"This is still a very successful movie," said Phil Contrino, chief analyst with BoxOffice.com.

Only 44 percent of moviegoers chose to see it in 3-D, which may reflect a shift away from the format by audiences, Hollis said.

"Age of Ultron" is projected to be the biggest film of the summer box-office season. Its competition for highest- grossing movie of the year is another Disney project, "Star Wars: The Force Awakens," which comes out in December. Disney also will release Marvel's "Ant-Man" and the Pixar film "Inside Out" in what is projected to be a record summer that tops $5 billion in U.S. and Canadian ticket sales.

"Age of Ultron" cost $250 million to make, according to Boxofficemojo.com.

With the film yet to open in China, analysts project "Age of Ultron" may outdo the first "Avengers" abroad. The first one generated $895 million in ticket sales outside the U.S. and Canada, reaching $1.52 billion in worldwide ticket sales.

The movie is running about 7 percent ahead of its 2012 predecessor in comparable foreign markets, Hollis said Sunday. When adjusted for currency fluctuations, "Age of Ultron" is 31 percent ahead.

BoxOffice.com had predicted "Age of Ultron" would take in $221 million in its opening weekend. Contrino said he expects the film to generate about $500 million in its domestic theater run, down from an earlier $567 million forecast. The first "Avengers" earned $623 million in domestic theaters.

The latest installment reunites Iron Man, played by Robert Downey Jr., Captain America, Thor, the Hulk and Black Widow, with actors Chris Evans, Chris Hemsworth, Mark Ruffalo and Scarlett Johansson reprising their roles.

When Tony Stark, Iron Man's alter ego, tries to jumpstart a dormant peacekeeping program, the villainous Ultron, played by James Spader, emerges. The film introduces new characters such as Quicksilver and Scarlet Witch, and sets up storylines for new installments that are planned in coming years.

Written and directed by Joss Whedon, who directed the first "Avengers," the installment scored well with critics, garnering 75 percent positive reviews, according to aggregator Rottentomatoes.com.
