Joaquin Phoenix back on Letterman
Joaquin Phoenix is to reappear on David Letterman's show for the first time since his infamous turn on the programme last year.
The CBS show said Joaquin was booked to appear on the Late Show in the US on September 22.
A documentary on Phoenix's attempt to become a hip-hop musician, directed by Casey Affleck, was released this month.
Phoenix's odd guest turn with Letterman in February 2009 was punctuated by uncomfortable silence and Letterman's request that the bearded Phoenix "tell us about your days with the Unabomber".
It drew about 8 million online views on YouTube and the CBS website. Letterman will replay that show in the US on Thursday.
Casey's movie, called I'm Still Here, opened in theatres last week.
