My guess is that you want the 1934 talkie version of this operetta, not the 1923 silent. It is available on DVD
. I can't vouch for the DVD, but I've seen the movie in the theater. For a light opera, it's surprisingly dark, and the pacing is often deadly slow. It does, however, have some good performances -- including Anna May Wong (a big star on both sides of the Atlantic but little-remembered today).
