Sylvester Stallone is back as Barney Ross for a fourth action star-jammed adventure, as he turns to a mercenary mix of old hands (Jason Statham, Dolph Lundgren, Randy Couture) and new blood (50 Cent, Megan Fox, Levy Tran) to take out a ruthless arms dealer (Iko Uwais) whose trafficking in nuclear warheads might do nothing less than spark World War III. Return to R-rated mayhem for the franchise co-stars Andy Garcia, Tony Jaa, Jacob Scipio. 103 min. Widescreen; Soundtrack: English.
