It includes "found footage" location shots of an Asian street full of rickshaws and a sailing ship on the Pacific Ocean. The costumes and sets are almost lavish. The film has a lengthy and complex plot, and includes intertitles. (from: https://en.wikipedia.org/wiki/Le_m%C3%A9nage_moderne_du_Madame_Butterfly)
