Also I don’t think you mentioned the significant Offenbach-Schneider biopic. La Valse de Paris 1950. I have seen this with subtitles on Australian television many years ago. It has great charm, and was totally delightful. With Schneider played by Yvonne Printemps and dressed by Christian Dior how could it be otherwise? It was not accurate, but it falls happily into the established (and surely fun? especially if you accept them as fictitious) vintage genre of musical fantasy biographical films and musicals of composers’ and impressarios’ lives including Lilac Time, The Great Waltz, The Great Ziegfield, Night and Day, Song of Norway etc etc.
Many of Offenbach’s best known arias were performed during the narrative, enough said!

I also saw an excellent French TV miniseries about Offenbach in the Second Empire, again on Australian TV again subtitled, again we are speaking decades ago, Les Folies Offenbach, with lots of Schneider and lots of Napoleon III too! ["Who could ask for anything more?"] The French made far far better historical TV series than the US at that date: impeccable settings and design, impeccable acting and production, but given the wider distribution of television as a family-based and accessible medium, some of the somewhat tedious, self-conscious and pretentious searching for avant garde and highly intellectualised/elite cultural effects as a benchmark of woke credibility that dogs both film and (especially) opera production in Europe is kept in check. I would be happy to see this series again.

Talking of operetta and moving popular culture, there was also a filmed version of La Vie Parisienne from the late 1970s, that received international cinematic release on the “arthouse” circuit. Partly it was filmed live outdoors at historic Paris sites. I can find no clips and few images apart from the poster on the internet with a short search, which is surprising given that there was, if memory serves right, a scene with women in full 1860s crinolines cartwheeling down one of the famous “passages” of Paris.
