David Letterman showed support for Stephen Colbert by posting a YouTube compilation of clips of him slamming CBS on "The Late Show."

The September event, coming to New York for the first time, will also include panel discussions with Robert Downey Jr., David Letterman and Richard Ayoade.

NEW YORK — Stephen Colbert has received support from his fellow late-night TV hosts following his cancellation by CBS, including from his predecessor. David Letterman, who was the host of “The Late Show” for 22 years, used his YouTube channel to post a video montage of the many times he ripped into CBS over the years for various reasons.

J oaquin Phoenix has apologized for his controversial 2009 appearance on The Late Show with David Letterman. Phoenix, in character for his role in the mockumentary I'm Not Here, answered Letterman's questions with mumbles and one-word answers, leaving the host and the audience confused.

The actor was promoting the mockumentary 'I'm Still Here' when he delivered one of the strangest interviews ever recorded for late night television.
