"Straight Outta Compton" easily maintained its box-office lead with an estimated $26.8 million in ticket sales over a sleepy late summer weekend at the multiplexes.
The N.W.A biopic, a much buzzed-about hit, dominated over the late August releases that often characterize Hollywood's dog days of summer. It has now made $111.5 million in two weeks.
The low-budget horror sequel "Sinister 2" fared the best of the new releases, opening with $10.6 million, according to studio estimates Sunday. Fox's assassin thriller "Hitman: Agent 47," the second attempt to adapt the popular video game, disappointed with $8.2 million.
Lionsgate's "American Ultra," starring Kristen Stewart and Jesse Eisenberg, also failed to spark much interest, opening with $5.5 million.
"Mission: Impossible â Rogue Nation" came in second with $11.7 million in its fourth week.
