Parkes/MacDonald Productions has acquired feature film and television rights to League Of Denial: The NFL, Concussions And The Battle For Truth.

Walter Parkes and Laurie MacDonald will produce the adaptation under the Parkes+MacDonald/Image Nation partnership with the Abu Dhabi-based company.

ESPN reporters Mark Fainaru-Wada and Steve Fainaru, winner of the Pulitzer Prize for his series of Washington Post articles on private contractors in Iraq, wrote the book.

The brothers investigate the dangers of head injuries in American football and the National Football League’s stance. The book formed the basis of an investigative documentary for PBS’ Frontline earlier this year.

Principal photography began last July on Parkes+MacDonald/Image Nation’s first project, I Am Malala. Davis Guggenheim directs.

The next project is The Fall Guy, which McG is scheduled to begin shooting on July 14 2014. Dwayne Johnson will star.
