Larchmont Boulevard was (and remains) a very popular place to film. Many of Harry Langdon’s antics from Saturday Afternoon (1926) were filmed at the corner of Larchmont and W. 1st Street.
Larchmont appears in many other silent films, including Harold Lloyd’s Hot Water (1924) and For Heaven’s Sake (1926), Buster Keaton’s Sherlock Jr. (1924), and Langdon’s His Marriage Wow (1925). Many 1927 – 1928 titles from the series of Weiss Brothers comedies featured on the Weiss-o-Rama DVD collection were also filmed on Larchmont.
