Not only have we been anxiously awaiting the return of Gotham’s favorite laughing anti-hero, but we now finally have our first proper good look at theJokersequel and his next descent into criminality withJoker: Folie à Deux’s first trailer.Joaquin Phoenixreturns to the groundbreaking role that earned him an Oscar win, but he’s also joined by legendary musician and fellow Academy Award winnerLady Gaga. Sincethe upcoming sequel is being billed as a romance, you’re able to probably guess what supervillain partner she’ll be playing.Joker: Folie à Deuxalso isn’t just a romance film either, as it’s been turning heads the past few months afterbeing labeled a “jukebox musical"of all things. Certainly an audacious move, but one that feels fitting forTodd Phillips' continuation of his risk-taking follow-up.

The firstJokervery much insisted on being its own thing, only having a few Easter eggs and references to the larger DC Universe.Joker: Folie à Deuxwill likely be following that same path, but there are still plenty of plot details and references that we can see inthe first trailer alone.

Joker: Folie a Deux

Joker: Folie à Deux explores Arthur Fleck’s ongoing struggle with his dual identity as he unexpectedly discovers love and unleashes his hidden musical talent. Set against a backdrop of societal unrest, Arthur’s journey intertwines personal transformation with chaotic encounters, leading to profound shifts in his life and the world around him.

Arthur Fleck Is Still in Arkham Asylum in ‘Joker: Folie à Deux’

The opening scene ofJoker: Folie à Deux’s trailer confirms that the film will pick up right whereJokerleft off. Where the first film ended with the clown formerly known as Arthur Fleck being brought tothe notorious Arkham Asylum(where he may or may not have killed a hospital employee), the trailer opens up with the reveal that Arthur is still there. While yes, he may or may not have escaped in between then since that’s something Joker is known to do, it’s in this legendary location ofBatmanhistory where his journey will continue.

‘Joker: Folie à Deux’ Changes Up Harley Quinn’s Origin Story

The trailer forJoker: Folie à Deuxdefinitively confirms thatLady Gaga is playing Harley Quinn. However, it’s very clear that the film will be making some changes to the iconic character’s origins. In the way it usually goes for Harley and Joker’s introduction, Harley was once an empathetic-to-a-fault psychiatrist who was working at Arkham Asylum. There, she inevitably meets Joker and finds herself being undeniably charmed and fascinated by one of the comic book world’s deadliest villains. She aids Joker in escaping the Asylum and joins him as his romantic partner in crime (though Joker andHarley’s relationship is typically more abusive than romantic).

Joker: Folie à Deuxalready makes some big changes to the usual story, asit doesn’t appear that Harley is a psychiatrist in this iteration. Perhaps she was before, but the trailer depicts her as a fellow patient of Arthur Fleck rather than a superior. She also appears to be familiar with Joker’s work, which gave Gotham’s impoverished people a voice, and rather than being repulsed by it, she finds it rather admirable.

The ‘Joker: Folie à Deux’ Trailer Teases the Film’s Elaborate Musical Numbers

A voice overheard early on in the trailer ofJoker: Folie à Deuxreads: “We use music to make us whole. To balance the fractures within ourselves.” Given that Arthur first sees Harley when she’s engaging in some sort of choir session at the asylum, it appears thatmusic is being used as a therapy method for the hospital’s patients. This seems to be the introduction of the film’s musical elements, and it’s pretty obvious how they are going to be utilized.

Clearly taking inspiration from classic movie musicals likeSingin' in the Rain, we see several sequences with bright colors and pristine backdrops where Joker and Harley conduct their performances. The first of these shown in the trailer quickly cuts to the two dancing on a stage and then to a busy Gotham street where a building is on fire, showcasing that these moments are occurring in their heads rather than in real life. One scene shows them dancing down courtroom steps where a man holdsa newspaper that shows Joker on the front page and “Free on All Charges.“Whether that’s reality or fiction is still up for debate. It might sound like a pretty big departure from the originalJokerfilm, but it is somewhat fitting given that the title character is very much an unreliable narrator.

Harley Is Directly Mirroring Joker From the First Film

Throughout various points of the trailer, we, of course, see Harley following in Joker’s footsteps. Some of these moments are literal, asshe’s directly copying some of his iconic moments from the first film. First, we see her using her fingers to mimic a gun before jokingly pulling the trigger, just like Arthur did in the firstJoker. Then, we see bothHarley and Joker doing an all-new rendition of the iconic stair dance, with them gleefully strutting down the steps with a big crowd watching them. Finally, we see Harley copyingthe ending of the first filmwith her using blood to give herself a violent, bright red smile.

Joker Is Fleeing from a Copycat

Speaking of mimicking, it also looks likeJoker is fleeing a Joker copycat in the first trailer. It’s more than just another guy in a clown mask, as this copycat is also decked out in the same yellow and burgundy suit he wore in the first movie. This certainlyadds credence to the fan theorythat Arthur Fleck is not the same Joker that Batman is destined to fight, but rather inspired the person who does take on that role. The Green Goblin himself,Willem Dafoe, even pitched a concept of him playing a Joker impostor for a possible sequel, so who knows? We certainly wouldn’t say no to Dafoe as The Joker, even if he’s a fake one.

The ‘Joker: Folie à Deux’ Trailer Ends With an Incredible Final Shot

This isn’t like a big shocking detail or anything, butthe final shot ofJoker: Folie à Deux’s trailer is really remarkable. The sequence sees Arthur Fleck once again incarcerated, with a woman (presumably Harley) visiting him. She uses some lipstick to paint a smile on the glass, where Arthur’s head perfectly moves into the frame to fit the symbolic facade. It’s evocative imagery, and it’s a shot that certainly suggests that the Todd Phillips follow-up is more than a simple cash-grab sequel.
