Despite the turbulence, Mel Gibson’s “Flight Risk” managed to open No. 1 at the box office with a modest $12 million, according to studio estimates Sunday.

Flight Risk,” an action thriller directed by Mel Gibson and starring Mark Wahlberg as a balding, unhinged pilot, landed in first place with $12 million from 3,161 North American theaters in its opening weekend.

The premise is simple: Michelle Dockery plays U.S. Marshal Madolyn, tasked with transporting wiseass accountant Winston (Topher Grace) on a prop plane from Alaska to Seattle. Daryl (Mark Wahlberg), their shady pilot, is secretly working for the bad guys and tasked with killing Winston before he can testify. That’s it. That’s the setup.

Elsewhere, "Mufasa" holds strong at second, "Presence" makes its box office debut, and "The Brutalist" expands to maintain its footing in the top 10.
