Joaquin Phoenix Schedules David Letterman Rematch

Mark September 22 down on your Tivo schedule as the day that Joaquin Phoenix will return to the Late Show with David Letterman, this time to promote his unsettling new documentary I'm Still Here. The actor/rapper last appeared on the show in February 2009 in one of the greatest late night segments of the decade. By the time the segment wrapped, the Late Show host was asking his cranky guest about the Unabomber and threatening to show up at Phoenix's house to chew gum. [Vulture]
