Lesley Goldberg, writing for The Hollywood Reporter: Two years after signing off CBS' The Late Show, David Letterman is returning to the small screen. The longest-serving host in U.S. late-night TV history is set to topline a new talk show for Netflix. The untitled six-episode series will premiere in 2018. Unlike The Late Show, each hourlong episode of the Netflix series will be prerecorded and feature Letterman conducting longform conversations with a singular guest as well as exploring topics on his own -- outside of the studio. A guest list has not yet been revealed. "I feel excited and lucky to be working on this project for Netflix. Here's what I have learned, if you retire to spend more time with your family, check with your family first. Thanks for watching, drive safely," Letterman said.
