LOS ANGELES, California: Sylvester Stallone and Jason Statham weren't enough to keep 'Expend4bles' from flopping in its debut. The fourth installment suffered the action-packed franchise's worst opening weekend while 'The Nun 2' remained on top of the box office for a third straight week, data firm Comscore reported on Sunday.

The Lionsgate and Millennium film, also known as 'Expendables 4,' pulled in a mediocre $8.3 million over the weekend. It starred several popular performers, including Stallone, Statham, Curtis '50 Cent' Jackson, Megan Fox and Dolph Lundgren. It's been nearly a decade since the franchise released a film, which opened with $15.8 million and eventually grossed $214 million globally.
