EXCLUSIVE: Jennifer Connelly is joining Josh Brolin, Miles Teller, Jeff Bridges and Taylor Kitsch in Granite Mountain (previously titled No Exit), the feature film based on the 20-member Granite Mountain Hotshots who fought the deadliest wildfire ever in Arizona’s history and were trapped on a mountainside in a circle of fire. The story of these true American heroes — 19 of whom died while trying to protect the lives of others — was written by Ken Nolan and Eric Warren Singer and will be directed by Joe Kosinski (Oblivion).

It’s known that in drafting the story, the filmmakers spoke to the lone surviving member of the 20-man crew, Brendan McDonough.

The movie is based on true events that were chronicled in a GQ article. Black Label Media (Molly Smith & Trent Luckinbill and Thad Luckinbill) and Di Bonaventura Pictures are producing for Lionsgate. Specifically, Lorenzo Di Bonaventura, Mike Menchel, Erik Howsam and Jeremy Steckler and Dawn Ostroff for Conde Nast Entertainment are producers.

Connelly is set to play the role of Amanda Marsh, the wife and “horse-whispering farrier” of the supervisor of the Tier One team of Hotshots.

The logline: “Always a Tier Two team cleaning up after the elite Tier One ‘Hotshots’ who follow the wildfires during the season, the Prescott Wildland Firefighters – under the tireless training and perfectionism of their Supervisor Eric Marsh – become the first Municipal firemen to become Tier One themselves. A tight family of twenty, they’re the lead when lightning ignites the dry tinder on the hills beyond Yarnell. When a storm moves in and the wind shifts, the fire reverses course and picks up incredible speed. By luck, one of the young Hotshots, Brendan makes it out… but Eric and the other nineteen members of the Granite Mountain Hotshots tragically perish.”

Connelly, who won a Best Supporting Actress Oscar for A Beautiful Mind, is repped by CAA and RMS Productions.
