Box office: ‘The Accountant,’ with Ben Affleck, finishes Friday at No. 1

“The Accountant” looks to be tallying up a win.

On its first day in theaters, the Ben Affleck financial thriller took in just over $9 million at the box office, according to estimates from Box Office Mojo — enough to vault past last week’s top-grossing film, “The Girl on the Train,” which slipped to No. 3 as the weekend began.

Friday’s performance by “The Accountant” — about an autistic math whiz who cooks books for criminal organizations — put the Warner Bros. picture on track to meet prerelease projections that it would gross $20 million to $25 million by Sunday.

At No. 2, comedian Kevin Hart’s latest concert film, “What Now?,” opened with $4.76 million in ticket sales, Box Office Mojo said, nearly half of its estimated $10-million production cost.

“The Girl on the Train,” starring Emily Blunt in an adaptation of Paula Hawkins’ hit 2015 novel, collected $3.9 million as it headed into its second weekend in theaters.

Director Tim Burton’s “Miss Peregrine’s Home for Peculiar Children” finished Friday at No. 4 with $2.32 million in ticket sales, while the Mark Wahlberg action film “Deepwater Horizon” rounded out the top five with $1.86 million.
