The Late Show With David Letterman will see a shake-up in the writing department when long-time writer and producer Matt Roberts is promoted to the post of Head Writer, effective immediately.

Deadline broke the news yesterday (Jan 18) that the shake-up is set to happen, with Roberts replacing previous head writers Justin and Eric Stangel, who have held their post at the top of the writing team for fourteen years. The Stangel brothers won't be losing their jobs with Letterman and Rob Burnett's production company Worldwide Pants though, instead they will keep their posts on the show as well as being given the chance to write new material for the production company, including potentially working on a new show together.

Rob Bennett spoke to Deadline following the announcement of the shake-up, saying, ”The Stangel brothers are going to remain with the show as part of the deal because we need them. These guys are as good as it gets,” adding, "For people like this super valuable to the show, this deal keeps these guys from walking."

Bennett clearly didn't want a repeat of the last time The Late Show had a writer shake-up, when former writers writers Carter Bays and Craig Thomas walked from Worldwide Pants following a contract dispute. Bays and Thomas then went on to create the long-running series How I Met Your Mother, which has received masses of praise since it went to air in 2005.
