Adrenalin runs high in the entertaining, action-heavy remake of the 2004 French film “District B13.” Starring the late Paul Walker in one of his last roles, “Brick Mansions” packs gunfights, car chases, acrobatic stunts and humor into one stylized package. In the urban ghetto of Detroit, which has been surrounded by a containment wall, narcotics officer Damien (Walker) goes undercover and teams with ex-con Lino (David Belle) to infiltrate a crew of criminals and defuse a confiscated bomb.
