When the oldest member (Christopher Walken) of a string quartet announces his retirement following a crushing Parkinson's diagnosis, the other members of the group (Philip Seymour Hoffman, Catherine Keener, and Mark Ivanir) begin to question their roles as personal resentments rise to the surface. Yaron Zilberman's A Late Quartet is a film that knows and feels comfortable in the world it inhabits, allowing the viewer to always feel they are learning something even during passages where the drama doesn't click or when story elements feel prolonged. It also functions as a fine vehicle for its adept cast.
