“Is It Real or Is It Mockumentary?” Headscratcher Comes to DVD

Did you see I’m Still Here (2010), the mockumentary chronicling Joaquin Phoenix’s supposed retirement from acting to try his hand at rap music? Well, what made that movie fascinating was how it was edited in such a way as to make it impossible to tell whether the Oscar-nominated thespian was faking his conversion to hip-hop artist. Eventually, Joaquin did return to making movies, exposing the inscrutable biopic directed by Casey Affleck as just an elaborate hoax.
