Joaquin Phoenix: Biggest Hoax of All Time!

Joaquin Phoenix did not grow a beard and subsequently lose his mind two years ago. It was for a movie. As we predicted.

And Phoenix’s strange appearance on “Letterman” in February 2009, just a few months after he “retired” from acting to become a rapper? Also a fake. Even worse: Letterman, who handled it like a pro, wasn’t in on the joke.

“It’s a terrific performance, it’s the performance of his career,” Affleck told the Times of Phoenix’s two-year portrayal of himself, on-screen and off-, as an aspiring rap star on the brink of ruin.

Critics apparently disagree, delivering crushing reviews that are a far cry from the praise 35-year-old Phoenix received for his Oscar-nominated performances in “Gladiator” and “Walk the Line.”

“I never intended to trick anybody,” Affleck told the Times. “The idea of a quote, hoax, unquote, never entered my mind.”
