LOS ANGELES — It’s victory for “Dunkirk” and “Girls Trip” at the box office this weekend. Both original and well-reviewed films smashed expectations and enticed diverse audiences to the theaters.

Christopher Nolan’s World War II epic brought in an estimated $50.5 million to easily top the charts, according to Warner Bros., while the raucous comedy “Girls Trip” broke the R-rated comedy slump of 2017 with $30.4 million to take second place.

“Dunkirk” was far from an inevitable summer success, but stellar reviews, awards buzz and hype around the film’s large-scale production helped drive people to the theater.

Audiences were 60 percent male and 76 percent over the age of 25 for the PG-13 rated film, while IMAX audiences represented 23 percent of the market share.

Drawing quite a different audience was the buddy comedy “Girls Trip,” starring Regina Hall, Tiffany Haddish, Jada Pinkett Smith and Queen Latifah as a group of girlfriends who head to New Orleans for a weekend of fun. The Universal film drew in an audience that was 79 percent female and 50 percent under the age of 30. Fifty-nine percent of attendees were estimated to be black.
