This is a pretty good, taut, realistic, gritty film-noirish film…
 Most of the film’s dramatic moments take place in the courtroom, but there is a backstory involving municipal corruption…
 Boomerang is the story of how the man who eventually became U.S. Attorney General, Homer Cummings, used the prosecutor’s office to prove the INNOCENCE of an arrested murder suspect. How often do you see that happen?
 …Lee J. Cobb, as the cop who changes his mind, is excellent, and so is Karl Malden, who has less to do. I’ve always loved Sam Levene… the cynical wisecracking reporter was made for him. Playwright Arthur Miller lived near where the film was shot; in the police line-up, he’s the tall man in the dark coat on the far left.
-Excerpts from IMDB reviews
The film was directed by Elia Kazan who got the New York Film Critic’s Award for this and Gentleman’s Agreement. Boomerang! got an Oscar nom for Best Screenplay (adapted by Richard Murphy). The story starts off w/ narration re: life in a seemingly idyllic community, which could be any town in America. The peace is shattered when an elderly Episcopal priest is shot on a street corner. When the investigation stalls, pressure is put on the cops to come up w/ a suspect. A reporter, Dave Woods (Sam Levene), writes a series of articles criticizing the city government for inaction. Many men are picked up for questioning, just b/c they wear a dark coat and light hat (as the killer is alleged to have worn). In a police line-up, seven witnesses identify John Waldron (Arthur Kennedy), a former WWII vet w/ no job, as the murderer. Waldron (who was carrying a gun) denies the crime. After being questioned by Chief Robinson (Lee J. Cobb), Det. White (Karl Malden in an uncredited role), and a psychiatrist, the suspect confesses. District Attorney Henry Harvey (Dana Andrews) is put on the case. His friends urge him to win the case and run for governor, while facts lead him to believe the suspect may be innocent.
Kazan aims for realism, making it seem like we’re watching events as they unfold. This film was shot on location and features many locals (non-actors) in the crowd scenes. Fans of Star Trek will recognize Jane Wyatt (AKA Spock’s mom); she plays Madge Harvey, the wife to the D.A. She’s the loving/supportive wife, but also on top of things. This is the film debut of Ed Begley; he’ll later appear in 12 Angry Men (w/ Cobb). Begley is a small-time bureaucrat; he sweats and acts nervous. Kennedy plays an ambiguous character, the police interrogate him for two days, depriving him of sleep until he breaks down. Cobb carries Kennedy over to a cot, as you’d do w/ a sleeping child. The second act of the film is the courtroom drama. You can rent this movie on YouTube.
