Famous climax: A chase through the Los Angeles storm drains, filmed more than a year before the sewer chase in The Third Man¹

Plot

The film opens with the shooting of a police officer during a robbery attempt at a radio shop in Los Angeles. The killer, Davis Morgan (Richard Basehart), is a burglar who listens in to police radio calls, which lets him stay one step ahead of the investigation. Sergeants Marty Brennan (Scott Brady) and Chuck Jones (James Cardwell) pursue the case under Captain Breen (Roy Roberts). Morgan shoots and paralyzes Jones during an attempted arrest, then removes the bullet from his own body at his apartment. A forensics officer, Lee (Jack Webb), matches bullet casings from later liquor-store robberies to the earlier shootings, and a composite sketch built from victims' descriptions is identified by an electronics dealer, Paul Reeves (Whit Bissell), who had unknowingly been handling Morgan's stolen equipment. The trail leads to Morgan's home, and he escapes through the attic into the city's storm drains, where he is cornered and shot.¹^•²

The film presents the police side with the apparatus of real investigation: case boards, ballistics comparisons, mugshot files, a composite sketch, and the laboratory.⁸ According to a printed foreword on the film's prints, the story drew on a case from the detective files of the Los Angeles Police Department, which also assisted in the picture's production.¹

The storm-drain finale

The climax pursues Morgan through the Los Angeles storm drain system, which the New York Times called "700 miles of hidden highways."¹ TCM states this was the first time the locale was used in a film, and that it later served as the lair of giant mutant ants in Them! (1954).⁵ The chase predates by more than a year the famous sewer pursuit of Orson Welles in Carol Reed's The Third Man (1950); Alvarez writes that the Los Angeles sequence both predates and surpasses the Vienna one, photographed by Alton with low-key source lighting.¹^•⁹

The real case

The film was inspired by the crimes of Erwin "Machine Gun" Walker, whose Los Angeles crime spree ran through 1945 and 1946.⁴ According to the Hollywood Reporter, the film drew on the killing of a highway patrolman by Erwin Walker, a former civilian employee of the Glendale Police Department.¹ Unlike his screen counterpart, who is fatally shot in the storm drains, the real Walker was captured by the LAPD, spent time on death row, was institutionalized for many years in a state hospital, and won his freedom several years before his death in the 1980s.¹ A blu-ray.com review notes that while Basehart's criminal appears to have been modeled on Walker, the film is not a historically accurate account of him.⁷

Direction: Werker and Mann

Although the credits name Alfred L. Werker alone, the film has long been associated with Anthony Mann, who had just made the Eagle-Lion noirs T-Men (1947) and Raw Deal (1948) with screenwriter John C. Higgins and cinematographer John Alton.⁵ Modern sources note that Mann completed the directing assignment for Werker.¹ The film historian Max Alvarez, author of The Crime Films of Anthony Mann (2014), investigated the question through interviews with people who knew Mann or worked on the film, including dialogue director Stewart Stern, and concluded that Mann was responsible for at least 22% of the film; his sequences include the murder of a policeman and the climax in the storm drains.⁹ TCM attributes the self-surgery scene, in which Morgan extracts his own bullet, and the nighttime shootout at the electric company to Mann's direction.⁵

Style and cinematography

The film is a leading example of the semi-documentary style that entered the Hollywood crime film in 1948, alongside Jules Dassin's The Naked City, which was released earlier the same year; both were shot on location, The Naked City in New York and He Walked by Night in Los Angeles.¹⁰ Reed Hadley's narration introduces the city and frames the police work in the manner of a true-crime file.¹¹

John Alton's black-and-white cinematography is the film's most celebrated attribute. The Film Society of Lincoln Center calls it one of Alton's crowning achievements, "an endless, anxious maze of urban shadows."³ TCM's survey of the film describes splintered shadows from Venetian blinds, street lights over wet pavement, and a match lit in a dark room, and notes that Alton's use of light has been compared to the lighting in Rembrandt paintings.⁵ Critics have described the film as balancing the emerging docudrama tenor against Alton's Expressionist imagery.²

Legacy and Dragnet

The film's most durable influence is on the police procedural. Jack Webb appears as Lee, a forensics specialist, and the dry interplay between the investigators played by Scott Brady and James Cardwell reportedly inspired him to create Dragnet.⁶ According to the AFI Catalog, Webb developed a friendship on the film with its technical advisor, LAPD Sergeant Marty Wynn, who suggested that Webb start a program using LAPD files and staying close to real police procedures; Webb's radio show Dragnet, based on Los Angeles police case files, led to the NBC television series that ran from 1952 to 1959 and was revived from 1967 to 1970.¹ One study of television noir calls He Walked by Night the most important noir semi-documentary because of its influence through Dragnet on American television in the 1950s.¹² MoMA places the film among the key works in the emergence of the psychotic killer as a recurring figure in postwar thrillers.⁶

Reception and restoration

On Rotten Tomatoes the film holds an 82% Tomatometer from 11 reviews and a 65% Popcornmeter audience score from more than 250 ratings.² Contemporary and modern critics have singled out Basehart's performance as the detached killer; DVD Savant's Glenn Erickson called the film one of the very best of film noir's second wave and rated it excellent.¹³ The UCLA Film & Television Archive and The Film Foundation restored the film with funding from the George Lucas Family Foundation, and it screened at MoMA's film-preservation festival in 2016 and the New York Film Festival in 2019.⁶^•³ Kino Lorber issued a 4K restoration on Blu-ray on 30 January 2024.⁷
