Oscar winner Sean Penn is in talks to topline the drama Cartel, Variety reports. He would play a father forced to protect his son after his wife is murdered. Univeral and Imagine Entertainment hope to roll cameras by summer. Penn is still said to be in negotiations to star opposite Naomi Watts in Doug Liman’s Fair Game as Ambassador Joseph Wilson, the husband of outed CIA agent Valerie Plame Wilson.
