The series will consist of six hour-long episodes that feature a single guest in conversation with Letterman -- a sort of long-form interview. However, he'll also go out into the field to explore topics and issues away from a desk. The series does not yet have a name.

Netflix has become a major player in the TV and film landscape, and this newest get for them makes it clear they're here to stay.
