“Joker: Folie à Deux” is one of the strangest sequels a major studio has ever financed: a courtroom musical grafted onto the body of a billion-dollar character study, directed by Todd Phillips and starring Joaquin Phoenix and Lady Gaga, with Brendan Gleeson, Catherine Keener, Zazie Beetz and Harry Lawtey. It is a film that seems designed to disappoint the people who loved the first one — and it means it.

Where the original was a closed, airless descent dressed in the costume of a comic-book movie, this one answers a simple question with a deliberately uncomfortable one. The first film asked how a society manufactures its monsters; the sequel asks what we do once the monster exists, and whether the man underneath was ever real to begin with. Phillips takes the most bankable villain in popular culture and refuses, again, to give the audience the spectacle it came for. This time the refusal is set to music.

The Plot

It is the trial of the century. Arthur Fleck awaits judgment for the murders that closed the previous film, held inside Arkham State Hospital while the city outside treats him as a saint, a symbol and an excuse for its own anarchy. Within those walls he meets Lee — Harleen Quinzel, a fellow patient who arrives already in love not with Arthur but with the Joker, the persona the crowd has built around him. Their folie à deux, the shared delusion that gives the film its title, becomes the engine of everything that follows: two people singing to each other across the gap between who they are and who they need each other to be.

The Musical Gambit

The songs are not production numbers in the Broadway sense; they are interior weather. When Arthur and Lee break into standards from the American songbook, the film is showing us the only place either of them can be happy — a fantasy with no exit. It is a genuinely bold idea, and it is also the choice that detonated the film’s relationship with its audience. People came for the man who burned a city down and were handed a fragile soul humming to himself in a cell. Phillips knows this. The whole structure is built to take away the catharsis the first film was wrongly accused of providing.

The Performances

Joaquin Phoenix returns to the role that won him an Oscar in the first installment, and he is, if anything, sadder and smaller here — a body folded around its own shame, a laugh that still escapes like a wound. He plays Arthur as a man being slowly convinced to abandon himself, and the performance is unbearably patient. Opposite him, Lady Gaga gives Lee a quiet, dangerous certainty; she is the true predator of the piece, in love with an idea and willing to discard the person who fails to embody it. As a singer she is, of course, extraordinary, but the best thing she does is hold back — letting the menace sit under the melody.

The Craft

Technically the film is immaculate. The framing is precise, the palette swings between the bruised greys of Arkham and the saturated unreality of the musical sequences, and the courtroom is staged like a theatre because, of course, it is one. If there is a flaw in the writing, it is how often the script leans on the first film, recapping and quoting itself until the sequel risks becoming a commentary on its predecessor rather than its own work. But the control on display is total, and the bleakness is earned rather than fashionable.

This is the film’s cruel and genuinely interesting thesis: the character outlives the person. The crowd, the media, the courtroom and the fans all need the Joker, and they will keep him only as long as he performs. The moment Arthur tries to step out from behind the mask and simply be a man, everyone — inside the story and, pointedly, outside it — turns away. “Joker: Folie à Deux” is, in the end, a film about the impossibility of being seen, dressed up as the most expensive anti-blockbuster imaginable.

Our Opinion

“Joker: Folie à Deux” sets out to obliterate hope and any possibility of redemption by degrading its protagonist to the very end, and it succeeds — brilliantly, and at real cost to itself. It is technically superb, fearlessly performed and intellectually honest about what it is doing, while also being airless, punishing and, by design, almost impossible to love. It is not a failure of nerve; it is a film that knew exactly how unwelcome it would be and made itself anyway. Admirable and exhausting in equal measure, it is as brilliant as it is darkly tragic.
