It’s great to see Dame Maggie Smith in another "Quartet" movie, and this one is certainly my favorite! The narrative unfolds within a retirement community specifically for musicians and vocalists, as preparations begin for their yearly fundraising event and the arrival of someone new. It's that newcomer who really stirs things up for the friendly trio of “Wilf” (Sir Billy Connolly), “Reggie” (Sir Tom Courtenay) and “Cissy” (Pauline Collins - who deserves to be a dame, without a doubt!). The iconic "Jean Horton," a former performer at La Scala, makes her entrance, and it’s revealed that she (Dame Maggie) was once married to "Reggie," which understandably upsets him. Simultaneously, the gala—under the direction of the excessively theatrical “Cedric” (Sir Michael Gambon)—is threatened with failure because their headlining act had to cancel. The three friends decide that reviving their famous quartet from "Rigoletto" might be the best way to rescue their home, but will they be able to put aside past grievances long enough to perform? For me, Pauline Collins is the standout; her character—a somewhat scatterbrained and kind-hearted woman with amnesia—perfectly connects the playful “Wilf” and the more anxious divorcees. The script provides some laughs, but it's really the characters that truly shine here. It’s easy to picture places like this existing for people who had a reasonably successful career while they were in the spotlight, only to find themselves with little to rely on as age took its toll, leaving them feeling alone and short of money. Dame Gwyneth Johns, the film's genuine vocal talent, enthusiastically participates in the humor, playfully mocking pretentious performers and also delivering an impressive rendition of her (original) "Vissi d'arte" from "Tosca." It’s admittedly somewhat predictable, but Dustin Hoffman prevents it from becoming overly sentimental, and everyone involved seems to be having a good time making a film intended for enjoyment rather than deep analysis.
