"Word has been received here of the death in San Francisco on Wednesday of Mrs. Rosalie Mohr, pioneer resident of this city and daughter of the late Dr. and Mrs. C. E. Remarque [...] She was the beloved wife of the late Michael Mohr, loving mother of Mrs. T. A. Clark, Normard W., Oscar H. and Harold L. Mohr," He received all his formal education in his hometown, flunking out of Lowell High School, then attending San Francisco Polytechnic for over a year before dropping out for a job in the film exchange.Knickerbocker, Paine (April 27, 1958). "Dope, Gangsters and S.F. Cops Meet in the Line-Up". San Francisco Chronicle. p. 14TW. Retrieved October 19, 2025. "It is fitting that the world premiere of the motion picture, "The Lineup," should be in San Francisco. [...] Its cinematographer, Hal Mohr, is a native of San Francisco, and its technical director was Inspector John Kane of the local police department [...] Mohr, who was born in a house at Van Ness and Vallejo, went to Lowell (and flunked out) and then to Polytechnic High."Maltin, Leonard (1971). Behind the Camera: The Cinematographer's Art. New York: Signet. p. 92. . "Mohr: [...] I finished my grammar school, and then in high school I went to Poly, and in my second year at Polytechnic, I get a side job—I cut school for about the last year, and never finished high school. I got a job in the film exchange, splicing film and inspecting films that would come back from the movie theaters."
From a young age, Hal Mohr wanted to pursue a career in cinematography because he was curious to learn about how to make pictures move onscreen. He worked as a photo finisher in a photo lab to gain experience with the camera. When he was 19 years old, he filmed his first movie, Pam's Daughter, which was never seen by the public because of problems with the motion picture distribution company.
In 1913, in an early example of an exploitation film peddled directly to theater owners, producer Sol Lesser hired Mohr to make The Last Night of the Barbary Coast. This film purported to show the last night of the depraved Barbary Coast red-light district of San Francisco before it was shut down by the police.O'Driscoll, Margie (1994) "SF Art World; Celluloid in the City by the Bay". San Francisco Art Institute Graduate Catalog, 1994-1996. p. 21. Retrieved October 21, 2025. "In 1913, in anticipation of the Panama Pacific Exposition, the San Francisco Examiner conducted a campaign to rid the city of prostitution. [...] Anxious to record the final night of debauchery, promoter Sol Lesser hired Hal Mohr to document 'The Last Night of the Barbary Coast.' While the 1400-foot long film did little to eradicate prostitution, Moving Picture World noted, 'Seldom has a two-reel feature aroused more interest among the critics.'" (The area was not closed down until 1917.Symanski, Richard (1981). The Immoral Landscape : Female Prostitution in Western Societies. Toronto : Butterworth. p. 12. . "The commercialized prostitution which enjoyed quasi-legal status in San Francisco’s Barbary Coast for more than 60 years was a financial pillar to the city and one of its main attractions. [...] When the red-light district was finally closed in 1917, scores of brothels, saloons and other dives were shut down and 1,000 prostitutes went into retirement or found other places to work.") This is now considered a lost film.Tarbox, Charles H. (1983). Lost Films 1895-1917. Los Angeles, CA: Film Classic Exchange. p. 140. . "Other films of this sort of which few details are available include The Lure of New York (gangsters); From Dusk to Dawn, featuring Clarence Darrow in a courtroom scene; films of the Harry Thaw murder case; Ten Nights in a Barroom; and The Last Night of the Barbary Coast, filmed in San Francisco."
Inspired by the moving shots in the Italian movie, Cabiria, Mohr developed a camera with special tracking abilities for his 1914 film, Pan's Mountain.Deutelbaum, Marshall, ed. (1979). "Image" on the Art and Evolution of the Film : Photographs and Articles from the Magazine of the International Museum of Photography. New York : Dover Publications. pp.216–217. . The following year, he moved to Hollywood and began working at Universal City to gain further experience in the industry.
In 1927, Mohr filmed The Jazz Singer for Warner Brothers.Maltin, op. cit., pp. 134, 135. "THE FILMS OF HAL MOHR [...] 19. THE JAZZ SINGER—Warner Brothers 1927—Alan Crosland"
Although Mohr mainly worked as a cinema portraitist on movies such as The Wedding March, A Midsummer Night's Dream, and the Technicolor The Phantom of the Opera, he was passionate about exploring the limits of the camera. Mohr shot in deep focus years before Gregg Toland – Bullets or Ballots and The Green Pastures were both shot in deep focus.Beach, Christopher (2015). A Hidden History of Film Style: Cinematographers, Directors, and the Collaborative Process. Oakland, CA: University of California Press. p. 63. . "Evidence that some cinematographers other than Toland were interested in achieving deeper focus can be seen in Hal Mohr's invention of a novel 'swinging lens-mount,' which he used in two of his 1936 films, Bullets and Ballots and Green Pastures. This lens mount allowed the lens to be rotated in such a way that the camera could maintain in clear focus 'everything from the immediate foreground to infinity.' Although Mohr's invention would seem to have been an important development in Hollywood cinematography, other DPs did not adopt it, and it quickly disappeared from the scene."
Mohr's other cinematographer credits include Little Annie Rooney (1925), The Big Gamble (1931), Cheers for Miss Bishop (1941), Another Part of the Forest (1948) and The Wild One (1953).Darby, William (1991).

Directing On May 1, 1936, The Hollywood Reporter revealed that negotiations were underway between Mohr and Universal Pictures whereby the noted cameraman could soon be making his feature film directorial debut. The deal was inked in less than 2 weeks, but it was another six months before the film to be directed was identified by the Los Angeles Times, that being an adaptation of the Eleanore Griffin novel, Class Prophecy. With Deanna Durbin then set to star (as had been and would be numerous others prior to the eventual signing of Virginia Bruce) the story was characterized as a "light trifle" with a well-worn plotline,Schallert, Edwin (1936). "Hal Mohr to Direct Class Prophecy". The Los Angeles Times. p. 10. Retrieved October 28, 2025. a characterization emphatically echoed following the March 1937 release of the film, When Love Is Young.
Yet despite understandable reservations about the film's hackneyed scenario, Mohr's treatment of that material, as witnessed at the film's March 12 preview screening at Hollywood's Pantages Theatre (documented by the trade publication, American Cinematographer), elicited "bouquets by both of the local film dailies". Variety, for its part, predicted "general audience approval as a program topper, with credit for its high average entertainment quality going to Hal Mohr for his first directorial job and to a dozen players for good performances," adding that "playing and direction give impressiveness to a rather old and timeworn tale" and that Mohr's first directing effort—as well as his "rating as associate producer" [the latter evidently not credited onscreen]—is "notably fine in getting fullest value from the material, scoring especially in the ingratiating comedy and deft blending of the musical and dramatic elements.""A.S.C. Members On Parade". American Cinematographer. April 1937. p. 140. Retrieved October 28, 2025.
The Hollywood Reporter is even less restrained in its assessment (subtitled "Hal Mohr Scores With Swell Cast"), which begins by dubbing When Love Is Young "sweet entertainment from start to hilarious finish [and] one of those little pictures that makes big noises at the box office," while reserving its biggest bouquets for the film's director. But the big news concerning this picture is that it marks a really auspicious directorial debut. Hal Mohr, long known as one of the industry’s ace cameramen, here tries his hand at direction and turns out a superb job. There are no tricks that he misses in development of characterization, and touch after touch show master light craftsmanship. Make way for an important new director.
The Reporter would revisit the subject one month later, offering a generous sampling of the New York critical response. While the nine papers represented were somewhat mixed regarding the work as a whole, the three that made mention of the film's direction were uniformly positive, starting with the Times crediting Mohr for keeping the conventionally plotted film both "fresh and crisply paced," the Daily News, which praises the entire cast while crediting its excellent ensemble work to Mohr's "alert direction", and the New York American, whose reviewer credits the "twinkling directorial touch of Hal Mohr [for making] this stenciled story [seem] not as stereotyped as it sounds”.Movie Reviews: The Great O’Malley; Class Prophecy. ‘’Rob Wagner's Beverly Hills Script’’.
When Love Is Young'''s story, as noted, was not remarkable in and of itself; moreover, that same attention to detail, lauded by critics on both coasts, had led Mohr, over the course of a 39-day shoot and post-production, to exceed by $54,000 the film's projected cost of two hundred thousandRollyson, Carl (2015). A Real American Character: The Life of Walter Brennan. : The University Press of Mississippi. . "Hal Mohr, better known as a cinematographer, was directing his first full-length film for Universal and proceeded at a very slow, deliberate pace, completing thirty-nine days of shooting on February 5, 1937, and bringing in the project at $254,000—$54,000 more than the original budget."—all of which may help explain why this first-time Hollywood helmsman never did get the opportunity to build on his promising rookie effort.
