Joaquin Phoenix quits acting?

According to the entertainment show Extra, Joaquin Phoenix has decided to quit acting.

The video above was shot last night at a Paul Newman benefit, and the star of Gladiator, Walk the Line and the forthcoming Two Lovers, said :

‘I want to take this opportunity… also to give you the exclusive and just talk a little bit about the fact that this will be my last performance as an actor… I’m not doing films anymore.’

When asked if he was being serious, Phoenix (who was being followed by his own camera crews), said:

‘Yeah. I’m working on my music. I’m done. I’ve been through that.’

Either this is some kind of elaborate joke or Phoenix might have some serious issues going on.
