40. The Expendables 2 (2012)
Action Hero: Barney Ross
The Plot: Stallone, Schwarzenegger, Statham, Willis, Li, Lundgren and Van Damme assembled for the ultimate super-team sequel--something about a rival mercenary, an arms-dealer and a WMD.
Most Action-Packed Set-Piece: Seemingly ploughing all their budget (and all their Semtex) into the opening scene, the boys drive into a non-descript military base and spend a good ten minutes shooting, blasting, kicking, punching, stabbing and exploding an entire army of extras.
