Four Brothers is a 2005 American vigilante 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 film is set in November, 2004, as evidenced by dialogue among the characters, the date on a recently deceased character's grave marker, and the date on a bank receipt shown in the film. The seemingly random murder of their adoptive mother, Evelyn Mercer (Fionnula Flanagan), at a Highland Park, Michigan convenience store, brings four brothers back home to Detroit, Michigan 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.
