I'M STILL HERE: haven't you gone yet?

I'M STILL HERE is a 1 hour 46 minute film which outstays it's welcome by an hour and 45 minutes.
A self-indulgent fake documentary about a self-indulgent character, it's as big a waste of space as the character that real life (minor) movie star Joaquin Phoenix pretends he's turning into.
Directed by his close friend and brother-in-law Casey Affleck this is the ultimate Hollywood inside joke, but frankly ever if you were actually there you'd still need to be coked out of your head to laugh.

The film follows Phoenix from his surprise 2008 announcement that he was quitting acting and going into the music business to become a hip hop artist. Affleck's camera records Phoenix's apparent mental disintegration as he pursues this unsuitable career goal, culminating in his legendary, incoherent appearance on 'The Late Show with David Letterman.'
The sequence with Letterman is the film's only genuinely funny moment, and that's because of Letterman not Phoenix. The rest of the film is slow, shapeless and tedious.
Now that we know the whole film was just a set-up there's even less reason to watch it than there was when we believed Phoenix really was coming apart.
