“Avengers: Infinity War” has maintained its staying power at the domestic box office. 
 
 In its third frame, the Disney and Marvel blockbuster earned a huge $61.8 million. Combined with a near-record $200 million launch in China, “Infinity War” earned $343.1 million worldwide this weekend, for a global cume of $1.6 billion. On Saturday, it became the second-fastest film to cross the $500 million mark at the domestic box office. 
 
 The superhero adventure has passed “The Avengers” ($1.519 billion), “Furious 7” ($1.516 billion), “Avengers: Age of Ultron” ($1.405 billion), “Black Panther” ($1.229 billion), and “Star Wars: The Last Jedi” ($1.332 billion) to become the fifth-highest grossing film of all time globally. 
 
 Two mom-led releases got a Mother’s Day boost. Melissa McCarthy’s comedy “Life of the Party” debuted in second with $18.5 million from 3,656 locations. The Warner Bros. and New Line film, directed by her husband, Ben Falcone, is currently averaging a 41% on Rotten Tomatoes, as well as a B CinemaScore. It marked one of the lowest openings for a McCarthy-starrer. In comparison, “The Heat” opened in 2013 with $39 million, “Spy” with $29 million in 2015, and “Tammy” with $21.4 million in 2014. 
 
 Meanwhile, Gabrielle Union’s “Breaking In” launched in third with $16.5 million in 2,537 locations. The thriller from Universal has a 27% rating on Rotten Tomatoes. The low-budget film produced by Will Packer cost approximately $6 million. 
 
 “It’s great to see a female-led, action-packed thriller doing so well at the domestic box office this Mother’s Day weekend,” said Jim Orr, president of domestic distribution at Universal Pictures. “We have an amazing partner in Will Packer. He constantly delivers quality titles that audiences cannot get enough of.” 
 
 The second weekend of Lionsgate and Pantelion’s comedy “Overboard” landed in fourth with $10 million, while the sixth weekend of Paramount’s “A Quiet Place” secured No. 5 with $6.3 million. “Overboard,” starring Eugenio Derbez and Anna Faris, remained steady in its sophomore outing, dropping just 31%. Its domestic tally currently sits at $29.6 million. John Krasinski’s “A Quiet Place” had one of the best holdovers of the weekend, declining just 18%. To date, the horror film has made $169 million at the domestic box office. 
 
 The year-to-date box office is up 4.9% from 2017, according to comScore. The box office is likely to see a boost in coming weeks as “Deadpool 2” opens May 18 and “Solo: A Star Wars Story” bows on May 25.
