Watch Ben Affleck and Jon Bernthal surprise Kelly Clarkson with cake and a bouquet of flowers for her birthday: 'Getting two handsome men to deliver it? What a birthday!'

Ben Affleck and Jon Bernthal discuss their real-life brotherly bond in "The Accountant 2."

Bernthal is great at playing a brash, straight-talking badass. His Braxton is the perfect foil to Christian, and when they’re on the road together, “The Accountant 2” finds its ideal form as a violent buddy action-comedy. One scene in which they get drunk at a country western bar is a particular highlight.
