Brent Lang Executive Editor of Film and Media Projected Picture Works, the production company founded by Sean Penn last year, has signed on to produce “Killers & Diplomats.” The political thriller tells the true story of four American missionary women who raped and murdered in El Salvador in 1980. It follows a young U.S. diplomat who cracked the case by cultivating an improbable source — risking everything to gather the key evidence. The film is based on an article by Pulitzer Prize winning journalist Raymond Bonner. “Killers & Diplomats” is from writers Michael Nourse and John Tyler McClain, whose screenplay was featured on the 2021 Annual Black List. It was developed by producers Jordan Foley and Jonathan Rosenthal of Mill House Motion Pictures. Projected Picture Works partners John Ira Palmer and John Wildermuth are producing with Penn, Foley and Rosenthal. Ray Bonner will executive produce with Yeardley Smith and Ben Cornwell of Paperclip Ltd.
