Phoenix Pictures and MRM Pictures are developing a feature version of Heraldo Munoz’s “The Dictator’s Shadow,” his tale of the Chilean dissident movement in the wake of Gen. Augusto Pinochet’s seizure of power in 1973.

Mikko Alanne has been tapped to adapt. Alanne previously adapted Martha Raddatz’s “The Long Road Home” for Phoenix and co-wrote Oliver Stone’s Vietnam War drama “Pinkville,” which United Artists ditched during the writers strike in 2007.

R.D. Miller will produce “The Dictator’s Shadow” for MRM, and Mike Medavoy, Arnie Messer and Edward McGurn will produce for Phoenix. MRM’s Tim Roth will exec produce and Jose Ignacio Cuenca will co-produce. Deal marks the first project in a long-term strategic partnership between Phoenix Pictures and MRM.

The adaptation will detail life in the opposition at a time when Pinochet’s secret police tortured and killed dissidents in Chile.
