Directed by acclaimed filmmaker Peter Berg, Patriots' Day is an account of the 2013 Boston Marathon bombing and the everyday heroes who inspired the world in the extraordinary hours that followed. The harrowing real-life drama will open in New York, Los Angeles and Boston on December 21, 2016. The film will open nationwide on January 13, 2017. Today, we have the first poster which celebrates the heroes behind this awful day that will be long remembered.

In the aftermath of an unspeakable act of terror, Police Sergeant Tommy Saunders (Mark Wahlberg) joins courageous survivors, first responders and investigators in a race against the clock to hunt down the bombers before they strike again. Weaving together the stories of Special Agent Richard Deslauriers (Kevin Bacon), Police Commissioner Ed Davis (John Goodman), Sergeant Jeffrey Pugliese (J.K. Simmons) and nurse Carol Saunders (Michelle Monaghan), this visceral and unflinching chronicle captures the suspense of the most sophisticated manhunt in law enforcement history and the strength of the people of Boston.

CBS Films put Patriots Day on the fast track back in March of last year. The production was in a race with 20th Century Fox's Boston Strong, which has another Boston native, Casey Affleck, attached to star in and produce. It looks like Patriots Day is the one that beat Boston Strong to the finish line. Both movies started production last year, though Boston Strong doesn't have a release date at this time.

Patriots' Day is based on a firsthand account of the 2013 Boston Marathon bombing by Boston Police Commissioner Ed Davis, with the help of research and footage shot on the scene by 60 Minutes. This will mark the first time that CBS Films has collaborated on a movie with 60 Minutes. Matt Charman, who wrote last year's acclaimed Steven Spielberg drama Bridge of Spies starring Tom Hanks, is behind the screenplay for Patriots' Day. Director Peter Berg, Matt Cook and Eric Johnson are also credited for helping write the script.

Mark Wahlberg will also produce alongside Scott Stuber, Stephen Levinson, Dylan Clark and Michael Radutzky. The story was envisioned as an "intense thriller" that spans the five-day manhunt for Dzhokhar Tsarnaev, that ended with a shootout in Watertown where he was eventually pulled from a boat. The bomb killed three people and injured 264, while the shootout claimed the life of one police officer and Dzhokhar Tsarnaev's brother Tamerlan, with several more injured.
