It seems that Joaquin Phoenix lived up to his Joker: Folie à Deux character's name on set.

Christian Bale's voice as Batman in the "Dark Knight" trilogy is infamous - and infamously bad for the vocal cords - but as it turns out, Joaquin Phoenix's unhinged laugh as Arthur Fleck in the "Joker" films was also a bit of a health hazard.

Warner Bros. has released the real final trailer fo À Deux . This is the second final trailer that they’ve released, and it features more new footage from the movie and teases the deranged story that it will tell.

Joaquin Phoenix’s Joker will make his big screen return alongside Lady Gaga. Not long after Joker director Todd Phillips confirmed he would be writing and directing a sequel, Gaga confirmed her casting by sharing a video of her and Phoenix’s silhouettes dancing via Instagram.

Joaquin Phoenix, the Oscar-winning actor known for his intense and immersive performances, recently demonstrated his playful side while filming the upcoming Joker: Folie à Deux. Now, you might be wondering how he did this while working on such a serious film.

Folie à Deux, recalled the time he and Joaquin Phoenix played a trick on Lawtey’s mom on the movie set. Phoenix stayed in full Joker makeup on set, even when not filming, so Lawtey said the actor played a trick on his unsuspecting mom.
