In a seminal version of his Death Wish characterization, Charles Bronson plays Alan Avery, a mild-manned L.A. schoolteacher who elects to stay mum after witnessing a gangland slaying. Forced to testify against the killers by the cops, Avery is turn terrorized by the Mob, who subsequently bring about the death of Avery's pregnant wife Edie (Gloria Henry). Meek and mild no longer, the outraged Avery embarks upon a one-man vendetta against the villains. The climax occurs in the posh mansion of gang boss Maxie Matthews (John Doucette)--who, as it turns out, isn't really worth killing. Based on a novel by Ovid Demaris, Gang War was one of a group of inexpensive second features released by 20th Century-Fox for the drive-in crowd.
