remained the top film in theaters in its second week of release, according to studio estimates Sunday.The A24 election-year gamble, the indie studio’s biggest budgeted film yet, took in $11.1 million in ticket sales at 3,929 theaters over the weekend.The $50 million film, set in a near-future US in which Texas and California have joined in rebellion against a fascist president, has grossed $44.9 million in two weeks.Its provocative premise – and A24’s marketing, which included images of US cities ravaged by war – helped keep “Civil War” top of mind for moviegoers.But it was a painfully slow weekend in theaters – the kind sure to add to concern over what’s thus far been a down year for Hollywood at the box office.Year-to-date ticket sales are down almost 20% compared to last year, according to Comscore.Going into the weekend, Universal Pictures’ “Abigail,” a critically acclaimed R-rated horror film about the daughter of Dracula, had been expected to lead ticket sales.It came in second with $10.2 million in 3,384 theaters.That was still a fair result for a film that cost a modest $28 million to make.
