Box office: 'Compton' No. 1; Zac Efron's 'We Are Your Friends' craters with $1.8M

The dog days of August saw Universal's box-office champ Straight Outta Compton remain No. 1 for the third straight weekend with $13.2 million from 3,142 theaters, while Christian drama War Room did far better than expected in earning $11 million from a small footprint of 1,135 locations to come in No. 2.

Elsewhere, Zac Efron's electronic dance music drama We Are Your Friends forged few friendships, debuting to a dismal $1.8 million from 2,333 locations, the worst opening of all time for a new Hollywood studio offering opening in 2,000 or more theaters, not accounting for inflation. That if there's any solace, it is that Warner Bros. paid a modest $2 million to distribute the film in North America on behalf of Working Title Films and StudioCanal (still, it's the latest in a string of summer titles from the studio to disappoint). We Are Your Friends, directed by Max Joseph(Catfish: The TV Series), placed No. 13 or No. 14.

We Are Your Friends stars Efron as a young DJ trying to break into the EDM scene and become a music producer. Wes Bentley and Emily Ratajkowski also star in the film, which earned middling reviews and a C+ CinemaScore from audiences.

Straight Outta Compton finished Sunday with a domestic total of $134.1 million in the latest victory for Universal, which is enjoying the biggest year in history of any Hollywood studio at the global box office.

Coming in No. 2 for the weekend was War Room, a needed win for Sony. It's also the top debut for a faith-based title since Heaven is for Real ($22.5 million) in April 2014. Sony released the movie via its faith-based TriStar/Affirm label.

War Room, nabbing an A+ CinemaScore, is the fifth collaboration from brothers Alex and Stephen Kendrick, the directing and producing team behind such Christian films as Fireproof andCourageous. The film, featuring an African-American cast, tells the story of a struggling family who searches for a solution through prayer. T.C. Stallings, Elizabeth Becka and Noel Baker star.

Among the weekend's other new entires, The Weinstein Co.'s political action-thriller No Escape, earning a B+ CinemaScore, grossed $8.3 million from 3,355 locations, putting it in a close race with Paramount's Mission: Impossible — Rogue Nation for the No. 3 spot.

No Escape, starring Owen Wilson, Lake Bell and Pierce Brosnan, posted a five-day debut of $10.3 million after opening Wednesday to get a jump on the competition.

Focus Features' Sinister 2, tumbling 56 percent in its second weekend to $4.7 million for a total $18.5 million, rounded out the top five.The Man from U.N.C.L.E. followed with $4.4 million in its third outing for a muted domestic total of $34.1 million.

Hoping to catch up with Titanic in North America, Jurassic World rolled out again in 350 Imax locations over the weekend, taking in $3.1 million. That puts the blockbuster's domestic total at roughly $643.1 million, still short of the $658.7 million earned by Titanic, the No. 2 film of all time behind Avatar ($760.5 million).

STX Entertainment's first title The Gift upped its domestic total to nearly $26 million in its fourth weekend, while Ant-Man finished Sunday with a North American come of roughly $169 million.

The specialty box office saw the debut of Craig Zobel's film adaptation of Robert C. O'Brien's dystopian novel Z for Zachariah, starring Chiwetel Eijofor, Chris Pine and Margot Robbie. Roadside Attractions opted for a day-and-date release in 31 theaters and on VOD, reporting theatrical grosses of roughly $56,000 (the movie is No. 6 on iTunes).
