Box office revenue this weekend hit its lowest level since the weekends following the September 11, 2001 terrorist attacks as Hurricane Harvey closed Texas theaters, Mayweather/McGregor snatched Saturday night viewers and a lack of new product closed out an historically slow August, according to the Hollywood Reporter.

Revenue for this weekend fell 45% from the same weekend last year. Summer box office sales have now slumped more than 14% from last year.

No new offerings cleared $5 million in ticket sales, leaving an opening for Lions Gate (LGF.A) holdover "The Hitman's Bodyguard" to snag the top spot with $10 million in sales. Animated family flick "Leap!" did the best of the openers, grossing just under $5 million.

Specialty box office openings were also soft, with "Ingrid Goes West" and "Good Time" each opening to $781,750 and $610,890, respectively in limited release.
