Joaquin Phoenix explains career change in new film
A movie chronicling JoaquinPhoenix`s transition from actor to rapper is set for release.
Joaquin, 35, baffled fans two years ago when he began making a series of bizarre public appearances, insisting he was to become a rap artist.
The star made an infamous appearance on The Late Show With David Letterman, where he appeared dazed and confused about who he was.
He also grew a scraggly beard and wore a series of scruffy outfits, which saw the end of him being considered a Hollywood heartthrob.
At the time, speculation was rife that the entire change of direction was a hoax, especially since his brother-in-law, actor Casey Affleck, was constantly following the star with a camera.
Casey, 34, insisted he was shooting the outbursts for a documentary, as opposed to a mockumentary.
The movie, titled I`m Still Here: The Lost Year of JoaquinPhoenix, will hit cinemas in September, with distributor Magnolia Pictures still insisting the movie isn`t a prank.
"It is going to get a lot of attention, but it is not some cheap stunt where they said, `Let`s do some wild stuff and film it,` " Magnolia president Eamonn Bowles told the American edition of OK! magazine.
Eamonn says the movie is an excellent piece of cinema and believes audiences will be surprised when they see it.
"It is extreme behaviour but really good filmmaking as well. Frankly, some of the behaviour is very extreme. But it is in the context of the insanity of being in Joaquin`s life for that period of time. It is a unique piece of work that is going to surprise people in different ways," he added.
Joaquin previously had an immensely successful movie career. His last role as an actor was in the 2008 drama Two Lovers, where he starred opposite Gwyneth Paltrow.
His greatest professional achievement was being nominated for an Oscar after playing musician Johnny Cash in 2005 biopic Walk the Line.
