Folie à Deux will see Joaquin Phoenix, 49, return as Arthur Fleck, also known as the Joker, and he attended the premiere with his stylish sister Rain.

Rain looked stunning in a brown velvet gown and accessorized with chic sunglasses as she posed with her brother.

The film, highly anticipated as the sequel to the 2019 Oscar-winning *Joker*, which grossed over $1 billion worldwide and became the highest-grossing R-rated movie of all time, is set for release on October 4.

In the new installment, Arthur Fleck is institutionalized at Arkham, awaiting trial for his crimes as the Joker.
