Los Angeles: Men in Black: International led the North American box office with $28.5 million in its opening weekend.
However, its ticket sales represent only half of what previous installments in the science-fiction series earned during their first weekend in theatres. The three previous Men in Black films opened with over $50 million.
Directed by F. Gary Gray, the latest Men in Black entry sees Chris Hemsworth and Tessa Thompson team-up as black-suited agents protecting the Earth from a series of alien attacks.
Men in Black: International had a larger footprint with foreign audiences, generating $73.7 million from overseas territories, bringing the film's global start to $102.2 million.
Universal and Illumination's The Secret Life of Pets 2 took in $23.8 million during its sophomore weekend, marking a 49 percent drop from its inaugural outing. The animated sequel has now earned $92 million in North America.
Disney's Aladdin claimed third place, adding another $16.7 million to take its domestic haul to over $263 million.
Dark Phoenix dropped to fourth place over the weekend, adding $9 million in ticket sales, a 72.6 percent drop compared to its first weekend in theatres.
Rounding out the top five is Paramount's Rocketman, which picked up $8.8 million in its third outing for a total of $66 million in North America. The biopic sees an inspired Taron Egerton dramatise the life of legendary singer Elton John.
The weekend's other new movie was New Line and Warner Bros.' Shaft, which came in sixth at the domestic box office with an underwhelming $8.3 million haul from 2,952 locations.
Starring Samuel L. Jackson, the film is a sequel Gordon Parks' 1971 classic. It reunites three generations of Shaft men, played by Jackson, Jessie Usher, and Richard Roundtree, who starred in the original 1971 movie.
