FilmNation Entertainment has sold out foreign rights on “Ironbark,” the upcoming Cold War dramatic spy thriller with Benedict Cumberbatch that was one of the hottest projects entering the market around the Cannes Film Festival.

42’s Ben Pugh and Rory Aitken (“In Darkness”) will produce the feature, alongside Adam Ackland (“Patrick Melrose”), SunnyMarch and FilmNation Entertainment. Josh Varney from 42 and Leah Clarke of SunnyMarch will executive produce.

Cumberbatch, an Oscar-nominee for “The Imitation Game,” is currently playing Doctor Strange in “Avengers: Infinity War” and is appearing in the Showtime mini-series “Patrick Melrose.”

It has been a hot Cannes for Filmnation, which sold out the world on Armando Iannucci’s “The Personal History of David Copperfield” and “355” with Jessica Chastain, Penelope Cruz, and Lupita Nyong’o. It also introduced Pedro Almodóvar’s “Pain And Glory” to buyers at the festival.
