"   Photo: They Are Going to Kill Us Productions  Last year, when Joaquin Phoenix grew that beard and anounced he was retiring from acting to pursue a rapping career and then went on late night TV sounding like a rambling, delirious cross between a drunk sailor and Oscar the Grouch and stuck his gum underneath David Letterman&amp;#039;s desk and Casey Affleck mentioned he was making a documentary of the whole thing called I&amp;#039;m Still Here, pretty much everyone thought, &amp;quot;It&amp;#039;s a joke, right?&amp;quot; But then the year went on and no one involved in the project would admit it was fake. Last month, posters for the movie started peppering the city, it&amp;#039;s release date (last Friday) neared and not a single promotional interview clarified whether or not the film was a documentary or mockumentary\u2014until today. Affleck just told the New York Times that Phoenix delivered the &amp;quot;performance of his career&amp;quot; and that he &amp;quot;never intended to trick anybody.&amp;quot; He continued, &amp;quot;The idea of a quote, hoax, unquote, never entered my mind.&amp;quot; No one told David Letterman, however, which should make for great late night TV when Phoenix returns to the show next Wednesday.
