Joaquin Phoenix certainly did an impressive, impeccable and magnificent job. I dedicate a lot to the role ... Fence that was prepared very well and he has given step by step explanation of how he was able to characterize himself in the best possible way for his role and how only the great actors do it: very professional. I am infinitely grateful that you have taken the time to investigate about the disorders, about the drugs but especially for the time that I dedicate to perfect a detail as important as the joker's laugh, such an shocking laugh full of pain, frustration, anger and In many cases of madness. A wonderful experience in the movie theater for a lot with a great message, which unlike what has been said, has left me thinking about the responsibility we have in a society that instead of helping feeds violence.
