OREANDA-NEWS Joaquin Phoenix told reporters why his Joker’s laughter turned out to be so “painful”. This was announced on August 31 by The Hollywood Reporter magazine.

The actor said that in a very short time he lost about 24 kg in weight and this helped him to enter the role.

“It turns out that it affects your psyche. You're starting to go crazy,” Phoenix said, adding that director Todd Philipps gave him a magazine with jokes that helped him uncover the character's behavior.
