Studio estimates Sunday put two movies in a tie for first-place with $13 million each: Jake Gyllenhaal and Michael Pena’s police story ‘‘End of Watch’’ and Jennifer Lawrence’s horror flick ‘‘House at the End of the Street.’’ Clint Eastwood and Amy Adams’s baseball tale ‘‘Trouble With the Curve,’’ opened with $12.7 million. Actual rankings will be determined Monday as studios release final numbers. It was another slow weekend for Hollywood, whose business has been sluggish throughout late summer. (AP)

Singer seeks help

Green Day’s Billie Joe Armstrong is headed to treatment for substance abuse. Sunday’s announcement by the band’s rep comes after the rock frontman had a meltdown onstage at the iHeart Radio Music Festival in Las Vegas. In a clip that has gone viral, Armstrong profanely complained that the band’s time was being cut short, then smashed his guitar. In a statement to The Associated Press, the band apologized for the incident and said their set was not cut short by Clear Channel, the host of the two-day festival. The Grammy-winning band also is canceling some of its promotional appearances. It is scheduled to release the album ‘‘Uno’’ on Tuesday. (AP)
