The upcoming production was announced in the 26 June 1926 Motion Picture News by its working title, The Grey Hat, adapted by F. Hugh Herbert from an unidentified French farce, recently purchased by Metro-Goldwyn-Mayer Corp. (M-G-M). The picture was to star Lew Cody and Joan Crawford under the direction of Robert Z. Leonard. An item in the 24 September 1926 stated credited Harry Rapf as producer.
       The 22 January 1927 and 29 January 1927 issues of Hollywood Topics noted that Renée Adorée had replaced Crawford, and Harry Millarde had replaced Leonard. Principal photography was scheduled to begin during the first week of the following month. Two weeks into filming, the 15 February 1927 New York Daily News announced the picture’s official title as On Ze Boulevard. Additional cast members included Tenen Holtz and Mack Swain. Also joining the production was actor Max Barwyn, as noted in the 9 March 1927 Variety.
       On 13 April 1927, Variety revealed that M-G-M had assigned director Christy Cabanne to re-shoot more than half of the picture. Articles in the 29 May 1927 New York Times, the 19 June 1927 [St. Louis, MO] Post-Dispatch, and the 9 July 1927 [Indianapolis, IN] News described one of the featured sets as a replica of the Longchamp Racecourse in Paris, France, populated with background actors dressed in the latest Paris fashions. The 18 June 1927 [Sacramento, CA] Bee reported that Renée Adorée missed several days of work due to an attack of influenza.
       On Ze Boulevard was released on 25 June 1927, followed by a New York City opening on 7 July 1927 at the American Roof. Articles in the 17 September 1927 and 12 November 1927 issues of Film Spectator later described the picture as “the biggest flop” of Lew Cody’s screen career. Some subtitles were said to be literal translations from French to English, with their “only merit” being that they were properly punctuated. One article blamed producer Harry Rapf for not giving the project sufficient attention, while the other concluded that M-G-M was incapable of producing a French farce, based on several prior attempts.
       According to the Library of Congress American Silent Feature Film Survival Database, this film is extant.
