Casey Affleck insists Jaoquin Phoenix documentary is real

We were skeptical at the start but apparently the documentary - which has been referred to as a mockumentary- Casey Affleck has made on his brother -in-law Joaquin Phoenix and his aspiring rap career is the real thing.

Rumors are now circulating that the documentary is full of controversial issues in Phoenix's life including his use of drugs, sex and nudity.

Last year Phoenix announced he was going to retire from acting and concentrate on making a go of his music career, but rap?

He was super as Johnny Cash in "Walk the Line" but rapping his way around the world doesn't seem very likely.

But according to Affleck the documentary will highlight how serious Phoenix is.

The movie, "I'm Still Here: The Lost Year of Joaquin Phoenix," has reached audiences already in an effort to find a distributor.

Reports are now surfacing that the content of the movie is slightly shocking. Apparently Affleck features Phoenix ordering call girls, snorting cocaine and having oral sex with a publicist.

Affleck tells America's ABC News, "I wanted to explore what I thought would be an interesting period in his life. He said he didn't want to act anymore, he wanted to try doing music, and that, right there, says something's going to happen...

"I had no idea what exactly was going to happen and all that would unfold and every day I spent with him on this journey. It ended up being more and more fascinating, more and more things happened that were both in the public spectacle and a very private internal implosion that I got to witness. It made for this unbelievable, one-of-a-kind movie.

“You'll find out what was happening in his life in that period - what was going on before he went on (sic), what was going on afterwards."
