Two undercover agents must work together to find out who double-crossed them in an international trailer for 2 Guns. Mark Wahlberg and Denzel Washington star as operatives who have been trying to work each other for over a year, neither of them knowing that they are both undercover, when a bank job goes awry and they find out whose money they really stole. Plus, we have six clips and a TV spot for director Baltasar Kormákur's action-thriller, in theaters August 2.
