Breaking Down Joaquin Phoenix’s 2009 Appearance On The Late Show
Reckoning With A Super Awkward And Creatively Misguided Appearance
During the production of Joaquin Phoenix’s 2009 mockumentaryI’m Not Here, Phoenix dove headfirst into method acting, including with his appearance onThe Late Show with David Letterman. The interview, eight minutes of Letterman trying to extract anything of substance from Phoenix, was excruciating for audiences and the host alike.
Phoenix, in his reflection on the events, said that he notified Letterman’s team that he’d be in character, and that he wanted Letterman to “lacerate” him. He didn’t want anyone to know going into it, so that the “performance” could be as authentic as possible.
That was the kind of intention… I just always wanted to get this reaction and see how I would respond to that. So it was beneficial for no one to know, except when needed.
