Joker: Folie à Deux R-rating has been confirmed, and it looks like it won't be for just one or two reasons.

It comes as no surprise to anyone that a sequel to Joker – the highest-grossing R-rated movie of all time – would also receive the same rating. Now we know how it's going to achieve that rating as it received the following disclaimer:

"Rated R for some strong violence, language throughout, some sexuality, and brief full nudity."

Joker hit theaters in 2019. Phillips' unique take on the character was also nominated for 11 Academy Awards, winning two of those. Joaquin Phoenix won Best Actor, while Hildur Guðnadóttir took him a golden statue for Original Music Score.

Phoenix returns to once again star in the sequel, and Phillips has returned to both write and direct. Alongside Lady Gaga's Harley Quinn, there are currently-unconfirmed reports of Zazie Beetz, Catherine Keener, Harry Lawtey, and Jacob Lofland joining the cast as well.

The film's title already feels like a solid fit for the characters. The term 'folie à deux,' or 'folly of two' is a French term that refers to a condition of shared psychosis or shared delusional disorder. Applying real-world medical terms to fictional characters can be rocky, but if ever there was a term to describe Joker and Harley Quinn, this sure seems like it.

Joker: Folie à Deux is currently scheduled to hit theaters on Oct. 4, 2024. The first trailer will be released on April 9.
