The trailer which you can check out below, will feature Irish actor Brendan Gleeson who appears to play a security guard. The film is a sequel to Todd Philips' 2019 thriller.
Joker: Folie à Deux sees Joaquin Phoenix reprise his role as the deranged villain The Joke aka Arthur Fleck, alongside queen of chaos Harley Quinn, played by singer Lady Gaga, whose character finds a kindred spirit in The Joker.
In this sequel, Arthur Fleck is institutionalised at Arkham Asylum, as he awaits trial for his crimes as The Joker.
The film shows Lady Gaga's Harley Quinn tell the Joker: "When I first saw Joker, when I saw you, for once in my life I didn't feel so alone anymore", before later adding: "You can do anything you want - you're Joker".
Gleeson's character can also be heard asking Fleck: "How about you Arthur, do you still think you're a star?".
The sequel also stars Zazie Beatz and Catherine Keener, while Steve Coogan joins the cast, with the trailer showing him interviewing The Joker.
Joker: Folie à Deux will receive its world premiere on August 28, before hitting Irish cinema screens on October 4, exactly 5 years after the first film, which won 11 Academy Awards, including a Best Actor accolade for Phoeinix.
The title of the film is also a French reference to when two intimately related people share symptoms of the same mental illness, such as delusions.
