Matthew Heineman’s A Private War will make its world premiere at the 43rd Toronto International Film Festival (TIFF). The screening takes place on Sept. 14 at Roy Thomson Hall.

The film marks the feature narrative debut of critically acclaimed director Matthew Heineman ( Cartel Land, City of Ghosts) whose previous work in documentary filmmaking has earned him an Academy Award nomination, two Primetime Emmys, and two DGA wins for outstanding directorial achievement in a documentary.

A Private War, a biopic based on the true story of award-winning war correspondent Marie Colvin, stars Rosamund Pike ( Gone Girl, Hostiles) in one of her most intense roles to date. Based on a blistering 2012 Vanity Fair article by Marie Brenner, the drama follows Colvin to the front lines of conflicts around the globe as she risks everything to reveal the truth. Pike is joined by supporting cast which includes Jamie Dornan ( The Fall, Fifty Shades of Grey ), Stanley Tucci ( The Lovely Bones, Spotlight), and Tom Hollander ( The Night Manager).

At a time when journalism itself is under attack, Marie Colvin is one of the world’s most celebrated war correspondents. She is an utterly fearless and rebellious spirit, driven to the front lines of conflicts around the globe to give voice to the voiceless, while constantly testing the limit between bravery and bravado. After being wounded by a grenade in Sri Lanka, she wears a distinctive eye patch and is still as comfortable sipping martinis with London’s elite as she is confronting dictators. Colvin sacrifices loving relationships and, over time, her personal life starts to unravel as the trauma she has witnessed takes its toll. Yet her mission to show the true cost of war leads her to embark — along with renowned war photographer Paul Conroy (Dornan) — on the most dangerous assignment of her life, in the besieged Syrian city of Homs.

TIFF runs from Sept. 6 to 16.
