There is an excellent chance that you saw the final official trailer for Arnold Schwarzenegger's The Last Stand in front of Skyfall. In case you missed it here it is again.
The Plot: A drug cartel leader busts out of a courthouse and speeds to the Mexico border, where the only thing in his path is a sheriff (Schwarzenegger) and his inexperienced staff.
The film features Arnold Schwarzenegger, Rodrigo Santoro, Genesis Rodriquez, Forest Whitaker, Jamie Alexander, Harry Dean Stanton, and Johnny Knoxville. The Last Stand is directed by Jee-woon Kim (I Saw the Devil).
Yes, I saw this one when we saw Skyfall and it's funny.
