Harry Brown is a 2009 British vigilante action-thriller film directed by Daniel Barber and starring Michael Caine, Emily Mortimer, Jack O'Connell, and Liam Cunningham. The story follows Harry Brown, a widowed Royal Marines veteran who had served in Northern Ireland during The Troubles, living on a London housing estate that is rapidly descending into youth crime. After a violent gang murders his friend, Harry decides to take justice into his own hands.


Elderly pensioner Harry Brown, a decorated Royal Marine veteran of the Northern Ireland conflict, lives on a London council estate infested with violent youth gang activity and illegal narcotics distribution. Harry spends most of his free time playing chess with his friend, Len Attwell, at a local pub owned by Sid Rourke. When the hospital phones about his wife Kath's imminent demise, Harry arrives too late as the pedestrian underpass shortcut is active gang territory. Kath is buried next to their thirteen-year-old daughter, Rachel, who died of pneumonia in 1973.
