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.

A marketing campaign that splashes Gibson's earlier acclaimed earlier films — but not his name — holds an unflattering mirror to this uninspiring action thriller.

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