Four Brothers is a 2005 American action crime film directed by John Singleton. The movie stars Mark Wahlberg, Tyrese Gibson, Andre Benjamin and Garrett Hedlund. The film was shot in Detroit, Michigan and Hamilton, Ontario, Canada. The seemingly random murder of their adoptive mother, Evelyn Mercer (Fionnula Flanagan), in a convenience store brings four brothers from Detroit, Michigan back home to find out what happened. Originally under the impression the crime was a simple "robbery-gone-wrong", the brothers soon discover that the robbery was merely a cover for what was, in fact, a "hit" put out on Evelyn. After this revelation, Bobby (Mark Wahlberg), Angel (Tyrese Gibson), Jeremiah (André Benjamin) and Jack Mercer (Garrett Hedlund) track down the hired guns who killed Evelyn. Refusing to say anything, they are unceremoniously executed by Bobby and Angel. The next day, Detroit Police Lieutenant Green (Terrence Howard) and Detective Fowler (Josh Charles) confront the brothers about the murders. Lieutenant Green warns them that their interference with Evelyn’s case is ill advised, and that it will eventually put them in over their heads.
