Any speculation about whether or not I'm Still Here, the documentary that features an aloof Joaquin Phoenix, is legit can officially come to an end. Director Casey Affleck has revealed that it was all a gag.
"It's a terrific performance, it's the performance of his career," says Affleck of Phoenix's role in the doc. Adding that, "I never intended to trick anybody."
Phoenix is scheduled for a new appearance on The Late Show with David Letterman on September 22. The actor's last trip to Letterman served as a launching point for I'm Still Here. The Magnolia release is currently playing in limited release.
