Well, that didn’t take long.

In a revealing interview with the New York Times, “I’m Still Here” director Casey Affleck admits that his new Joaquin Phoenix documentary is fake.

“It’s a terrific performance, it’s the performance of his career,” Affleck says of Phoenix’s bearded hip hop persona.

The Magnolia Pictures documentary, released Friday, features the Oscar-nominated actor performing a number of racy stunts, including snorting cocaine off the breasts of prostitutes.

But Affleck says the entire documentary was a postiche.

“The idea of a quote, hoax, unquote, never entered my mind,” he says. “I never intended to trick anybody.”

Phoenix, who famously appeared dazed and confused on David Letterman, claimed that his acting career was over in the film.

“We wanted to create a space,” Affleck says of the fabrication. “You believe what’s happening is real.”

“I’m Still Here” is currently playing in 19 U.S. cities and expands to 120 cities tomorrow.
