LOS ANGELES » The boys from Compton smashed opening weekend expectations, while the stylish "The Man From U.N.C.L.E." struggled to find its footing.

Universal’s N.W.A. biopic earned an astonishing $56.1 million in its debut, according to studio estimates Sunday.

Director F. Gary Gray’s well-received film charts the formation and rise of the influential rap group. It cost just $29 million to produce.

N.W.A. members Dr. Dre and Ice Cube served as producers on the film, which has Ice Cube’s real son O’Shea Jackson Jr. playing his father. Dr. Dre also released the companion piece "Compton," — his first new album in 16 years.

Nick Carpou, Universal’s president of domestic distribution, said they were "elated" with the results. Universal had previously predicted a very conservative $25 to $30 million opening.

"It really struck a chord with audiences. It’s a story that is resonating right now," said Paul Dergarabedian, Rentrak’s senior media analyst. "It was one of those records that was an important work and a very important expression of a particular viewpoint. To this day, that album has so much power."

Beyond the fandom around N.W.A. and the timeliness of the themes, Universal also launched a clever marketing campaign around the film, "Straight Outta Somewhere," which allows social media users to insert photos in the iconic "Straight Outta Compton" album cover and write in a hometown of their choosing.

There have been over 5.4 million downloads to date and it trended No. 1 across Facebook, Twitter and Instagram for two days in a row.

"We’ve got the best marketers in the business and they understand their audiences," Carpou said. "The good news here is it attaches to a product that we’re exceedingly proud of."

According to exit polls, audiences for the R-rated film were evenly divided between genders, 51 percent were under the age of 30, 46 percent were African-American and 23 percent Caucasian.

Meanwhile, Warner Bros. PG-13-rated adaptation of the 1960s television series "The Man From U.N.C.L.E." debuted in third place, behind "Mission: Impossible — Rogue Nation," with a sluggish $13.5 million.

"I was hoping for a little higher number, quite frankly," said Jeff Goldstein, executive vice president of domestic distribution for Warner Bros. The goal had been a modest $15 million. The period spy thriller will have an uphill battle to make up its $80 million production budget.

"(Director) Guy Ritchie made an original and fun movie. Eighty-six percent of our audience was over 25 and 39 percent are over 50," he said. "Older audiences, we all know, don’t rush out opening weekend."

"The Man From U.N.C.L.E." stars Henry Cavill and Armie Hammer as a pair of American and Russian agents in the fashionable Cold War-era film.

Goldstein noted that they weren’t able to attract a significant younger audience, who are likely not familiar with the source material. The 7 percent who did turn out gave the film a favorable A- CinemaScore, and Goldstein hopes that word-of-mouth will spread in the coming weeks.

Fox’s "Fantastic Four" plummeted to $8 million to take the fourth place spot, while "The Gift" took fifth with $6.5 million.

But it’s Universal’s weekend to celebrate once more in what has become a banner year for the studio. Universal crossed the $2 billion mark domestically on Saturday — four months ahead of previous record-holder Warner Bros.

"Straight Outta Compton" is Universal’s sixth film to open over $50 million in 2015 and broke the August record for an R-rated opening.

"If you were to create a blueprint for how to perfectly execute a box office year, they’ve done it," said Dergarabedian.
