Who Plays Harley Quinn and Who Returns as the Joker?
Lady Gaga as Harley Quinn
Variety exclusively reported Lady Gaga’s casting in 2022, confirming her portrayal of Harley Quinn. The character draws from established comic lore yet represents a reimagining specific to this cinematic universe. Gaga’s involvement necessitates significant vocal performance given the film’s musical structure, distinguishing her interpretation from previous live-action portrayals.
Joaquin Phoenix Reprises Arthur Fleck
Joaquin Phoenix returns to the role that earned him the Academy Award for Best Actor in 2020. Sources indicate Phoenix discussed the sequel’s musical elements in interviews, emphasising the “folie à deux” dynamic—a shared madness between his character and Gaga’s Quinn that drives the narrative forward.
Both lead actors underwent extensive preparation for the film’s musical sequences, with Phoenix noting the challenge of integrating song into Arthur’s psychological journey.
Which Actors Are New to the Sequel?
Brendan Gleeson’s Addition
Casting reports confirm Brendan Gleeson joins the ensemble in a key supporting capacity. While Variety initially announced his involvement, specific character details remain unspecified. Industry speculation suggests he may portray a counsellor or authority figure within Arkham or Gotham’s institutional framework, though this awaits official confirmation.
Catherine Keener Joins
Catherine Keener’s casting was confirmed through production timelines and casting announcements. Warner Bros. press materials acknowledge her participation, though her specific role remains undisclosed. Reports suggest she may portray a legal or institutional figure interacting with Arthur Fleck during his incarceration or trial proceedings.
While Gleeson and Keener’s involvement is confirmed, specific character names and plot functions remain undisclosed pending official studio release.
What Supporting Roles Have Been Confirmed?
Beyond the principal quartet, IMDb listings and production reports confirm Zazie Beetz’s return as Sophie Dumond, the neighbour who featured prominently in Arthur’s delusions during the first film. Her return suggests the sequel may address unresolved narrative threads regarding her character’s fate.
Director Todd Phillips appears in a cameo capacity, continuing his tradition of brief on-screen appearances. However, no comprehensive supporting cast list has been released, leaving numerous Gotham residents and potential Arkham inmates unconfirmed.
Robert De Niro’s involvement as Murray Franklin remains unconfirmed for the sequel, despite his pivotal role in the 2019 original.

How Does the Cast Connect to the Original Film?
The sequel maintains direct continuity through Joaquin Phoenix and Zazie Beetz, whose characters survived the events of the 2019 film. Beetz’s return as Sophie Dumond proves particularly significant given the ambiguous conclusion of her storyline, which suggested Arthur’s relationship with her may have been delusional. Her confirmed presence indicates the sequel addresses these unresolved narrative threads.
Lady Gaga’s introduction as Harley Quinn represents the most substantial casting departure, bringing a character never before seen in this specific cinematic universe. This addition facilitates the film’s shift from psychological thriller to musical thriller, requiring vocal performances absent from the original. The Cast of Paddington 3 – Returning Stars and New Faces demonstrates similar franchise evolution strategies, though Joker: Folie à Deux pursues a distinctly darker tonal palette.
The absence of Robert De Niro’s Murray Franklin, whose murder marked the original’s climax, would significantly alter the ensemble dynamic, though his potential return remains unverified. Similarly, Frances Conroy’s Penny Fleck and Brett Cullen’s Thomas Wayne appear unlikely to return given their characters’ fates, leaving Phoenix and Beetz as the primary carriers of narrative continuity.
