A trailer for the much-anticipated film I'm Still Here: The Lost Years of Joaquin Phoenix - which documents the actor's recent erratic behaviour - has been released onto the web. The teaser trailer confirms reports that Phoenix's brother-in-law Casey Affleck was filming a movie about the enigmatic star, however, rumours that the production is indeed a fake 'mockumentary' remain unfounded.
The film has been shrouded in mystery since Phoenix began his bizarre change in persona in October 2008, announcing that he was to retire from acting in order to pursue a career in rap music. The OSCAR nominated star, best known for his role alongside Russell Crowe in Gladiator, soon began to sport a wild beard, and during a guest spot on The Late Show with David Letterman he appeared aloof and dazed, often mumbling his answers and ignoring the presenter. Suspicions that the actor's behaviour may have been a publicity stunt began to arise in various media outlets, but Phoenix and Affleck vehemently denied such rumours, and continue to do so.
The Los Angeles Times reports that the film sees Phoenix trying to persuade an uninterested Sean Combs aka P DIDDY to produce his new rap album - the movie debuts at the Venice Film Festival in September 2010.
