Variety reports that Edward James Olmos is set to play Papi Greco, a dangerous Mexican druglord who faces off against the two lead protagonists. Nothing is confirmed as of yet, but the actor - best known for recent roles in
Battlestar Galactica,
Dexter and
The Green Hornet - is in negotiations. The big screen adaptation of the Boom! Studios title has already signed up Mark Wahlberg and Denzel Washington (as a Navy Seal and DEA agent respectively who both work together to steal millions of dollars from the CIA without knowing that each is doing so undercover). They end up taking on their double crossing associates in a film which has also seen Bill Paxton and Paula Patton join the cast.
