Todd Phillips is getting the last laugh, as Joker 2 — Joker: Folie à Deux — will come to cinemas on 4 October, 2024.

Following in the bloody footsteps of 2019’s original, the Hangover filmmaker is returning to direct a sequel to the psychological thriller. Joaquin Phoenix also returns as Arthur Fleck, who takes on the mantle of the titular Clown Prince of Crime.

Joker left us with more questions than answers, but with the first movie being pitched as a standalone that wasn’t connected to the worlds of DC, many thought the story ended here.

It’s not the typical Batman movie you might expect, and with Joker bagging Phoenix an Academy Award for Best Actor, there are equally high hopes for Joker: Folie à Deux to perform.

If you’re ready to put on a happy face, here’s everything we know about the Joker 2 release date, cast, plot, and more.

Joker 2 release date

Joker: Folie a deux is due to hit cinemas on 4 October, 2024.

Warner Bros. has a packed slate of DC movies on the way, with everything from The Batman Part II to The Flash taking us far beyond 2023.

Joker 2 cast

Surprising no one, Phoenix will once again be slathering on the grease paint as Arthur Fleck. 2019’s Joker included an all-star cast that saw the lead share the screen with the likes of Frances Conroy, Robert De Niro, and Zazie Beetz. When it comes to returning cast members, there aren’t many options.

Lady Gaga has also confirmed she will appear alongside Joaquin Phoenix as Harley Quinn in the upcoming sequel. The Chromatica singer shared a red and black post to Instagram in August 2022 which was accompanied by the film’s scheduled release date.

Phillips, who has reunited with writer Scott Silver for the project, also shared the video, captioning it “cheek to cheek”.

On Valentine's Day 2023, the first look at Gaga as Harley Quinn was shared online by the singer, and a month later, she was first spotted on set outside the New York State Supreme Court Building.

At the start of April, Gaga was photographed shooting scenes at the famous New York steps that Joaquin Phoenix's Arthur Fleck danced down in the first movie.

One cast member who has seemingly confirmed he would return in Joker 2 is Justin Theroux. The actor made a blink and you'll miss it cameo in the first film as Ethan Chase, a guest on Murray Franklin's chat show, and in April 2023 he shared a photo on Instagram with Todd Phillips and Lady Gaga with the caption 'Midnight jokers' and '#thatsawrap'.

There’s a chance Zazie Beetz could return as Sophie, as the movie's cinematographer confirmed that despite her ambiguous fate, Fleck didn't kill her. The infamous deaths of Thomas and Martha Wayne seemingly count Brett Cullen out as Thomas Wayne, but remember the notion that he's Arthur's father.

The unreliable narrator of Joker means there’s a chance De Niro’s Murray Franklin wasn’t gunned down on live television, but we’d be surprised if he’s back.

Looking at more likely inclusions, Douglas Hodge could also reprise his role as Alfred Pennyworth, while Dante Pereira-Olsen’s young Bruce Wayne makes sense if Folie à Deux wants to explore the origins of Batman and Mr. J’s toxic relationship.

Brendan Gleeson, Catherine Keener, Jacob Lofland and Harry Lawtey have all been confirmed for the film in unconfirmed roles.

Finally, with Willem Dafoe talking so much about Joker — and even throwing his ideas around for a sequel — who wouldn’t want to see the Green Goblin actor join the unhinged party?

Joker 2 plot

The Hollywood Reporter described Joker 2 as a musical, which would be a massive departure from what came before, but to be honest, something typically Joker-esque.

The ending of Joker left things on something of a cliffhanger. An incarcerated Fleck was locked up in Arkham State Hospital at some unknown point after he incited riots across Gotham City. Fleck broke free after possibly murdering his therapist, so it’s likely Folie à Deux will follow him on the run as he continues his descent into becoming Joker.

The concept of a musical is another interesting one, suggesting that Joker 2 could follow in the footsteps of everything from Buffy the Vampire Slayer to The Boys having musical episodes. It also leans further into the idea we’ll dive deeper into Fleck’s mind this time around.

Interestingly, the title of Folie à Deux could hint at where things are heading. The title translates as a "delusion or mental illness shared by two people in close association,” so it sounds like Fleck will be sharing the screen with someone else.

Whether it’s the dual personality of Fleck and Joker or a direct reference to Batman/Bruce Wayne having a bigger part to play in Arthur’s evolution, there’s one more popular idea.

There's someone else other than Batman that shares their life with the Joker, and Folie à Deux is the perfect opportunity to introduce Harley Quinn to this dark and brooding world. Just like Dr. Harleen Quinzel worked at Arkham Asylum, Joker’s ending perfect sets her up.

With Joker standing on its own much like Reeves’ The Batman, it’s doubtful Margot Robbie will make the leap from the Suicide Squad movies for Joker 2. The topsy-turvy nature of Joker’s narrative means it’s not completely outside the realms of possibility.

In 2019, Phillips said he’d envisioned Joker as the first of three movies. It just so happens 2020’s Batman: Three Jokers comic series included three versions of the villain, which could play out in live-action.

When Dafoe made a mythical pitch for Joker 2, the star said, “There is something interesting about, like, if there was a Joker imposter. So it would be possible to have not duelling Jokers but someone that says to be the Joker that isn't the Joker."

Dafoe imagined a plot where someone was imitating what Fleck did, which would effectively make our tragic anti-hero into a full-blown hero hunting down an even more psychotic Clown Prince of Crime.

Before Joker came out, there were questions about the age difference between Fleck and Bruce Wayne, leading to theories that this version of the Joker isn’t the one Batman ends up fighting. If you aren’t convinced, remember the Wayne’s were watching Zorro, The Gay Blade, which featured the original Zorro training his gay twin as the next hero.

Could we see Phoenix pulling double duty as Arthur and a twin brother? Probably not, but multiple Jokers is an idea that’s picking up steam. Taking a leaf out of the Marvel Cinematic Universe’s book of world-building, Phoenix’s Fleck could mentor Barry Keoghan’s Joker from The Batman?

However, Reeves and Phillips seem to be keeping their outings as separate entities from anything in the Worlds of DC.

Joker: Folie a deux is in cinemas on 4 October, 2024.
