All the little specifics are finally starting to fall into place for A Late Quartet. The indie from Yaron Zilberman has been speculated about since Ethan Hawke boarded to play a depressed, cheating second violinist back in August, but now he’s out and his When The Devil Knows You’re Dead co-star Philip Seymour Hoffman is in.

According to IndieWire, details beyond that are a little scarce, but Christopher Walken and Catherine Keener may also be in. If that’s the case, we could be looking at a serious future Oscar contender, provided it gets enough distribution to be noticed.

The basic plot follows a renowned string quarter in a period of confusion after their leader is diagnosed with Parkinson’s Disease. All of the members have their own personal problems and each deal with the group chaos in very different ways. We still don’t know who would be playing what roles. Based on age, Walken would seem the likely candidate to be the quartet’s leader, but Hoffman seems like the logical choice to play the tragic role, at least based on acting strengths. We may not know all the details, but we certainly know enough to be very interested.
