Tell me if you disagree, but this has to be a hoax, right? Joaquin Pheonix "retires" from acting.... so that he can become a rapper. And his brother-in-law celeb, Casey Affleck, is directing a documentary about his transition.
Consider the evidence:
#1) He gives a scoop to E! Entertainment of all places that he's retiring from the acting world and pursuing a career in music.
#2) In a follow-up interview, he affirms (in a less-than-sober manner) that he has indeed retired from acting, that there's more to his "artism" than film, and that it's, like, greener pastures.
#3) In a clearly stoned-out-his-gord performance, he hops up and down like a child, points the mic at the audience inviting them to shout the lyrics to a song he's rapping for the first time, and in the end, falls on his ass walking off the stage:
My theory: he and Casey decided to create a documentary hoax, seeing how many sheep would willingly buy into the idea that he's fallen off the wagon and become a rapper. What's even more interesting: how could all of those simps in the club actually believe that they're listening to good music (when he's clearly intentionally trying to be the worst rapper in the world).
