Pixar's Finding Dory floated atop the box office for the third weekend in a row, besting a handful of new releases including Steven Spielberg's floundering The BFG, industry estimates showed on Sunday.
Dory, voiced by Ellen DeGeneres, follows a forgetful fish on a quest to find her parents, much as she did as a supporting character in the 2003 animated hit Finding Nemo.
The film, only in its third week in the theatres, made $41.9 million, for a total of $372.3 million in the United States since its debut.
Dory stole weekend glory from three new releases, including The Legend of Tarzan based on the early 20th century novel by Edgar Rice Burroughs.
It made $38.1 million at the box office.
In third was The Purge: Election Year, a gruesome sci-fi action horror film about an annual ritual in which crime, including murder, is allowed for 12 hours.
The third installment of the Purge series follows a police officer (Frank Grillo) who is tasked with protecting a senator who is running for president (Elizabeth Mitchell) while she is targeted for death after vowing to end the bloody ritual.
The film, timed to coincide with the 2016 election year, comes just months before Americans cast their votes in November for the next President. It earned $30.9 million.
The BFG, a fantasy-adventure adaptation by Spielberg of the beloved Roald Dahl classic about a girl who befriends a giant, came in fourth with a disappointing $19.6 million, according to industry tracker Exhibitor Relations.
The estimates, which covered Friday to Sunday, were posted in the middle of the US Independence Day weekend, with figures that incorporate the Monday holiday set to follow.
The timely Independence Day: Resurgence dropped to fifth place for its second week in theaters, cashing in $16.5 million.
A sequel to the 1996 humans-vs-aliens summer blockbuster, the latest installment is a second helping of space invaders and special effects that has been widely panned by critics.
Central Intelligence was sixth at the box office, with $12.3 million. The action-comedy about a spy who recruits a high school buddy for a caper stars Dwayne 'The Rock' Johnson and Kevin Hart.
