I want to know the answer to the following question:
What year was  La valse de l'adieu released?
All the background I'm provided with is that "Other film treatments have included: La valse de l'adieu (France, 1928) by Henry Roussel, with Pierre Blanchar as Chopin; Impromptu (1991), starring Hugh Grant as Chopin; La note bleue (1991); and Chopin: Desire for Love (2002).". Is that enough to answer the question?
Answer: yes
