In August 2008, Robert Llewellyn appeared on Seattle public television station, KCTS 9. In an interview, he revealed that BBC Worldwide, in collaboration with another party, had invested in one hour of new Red Dwarf to be filmed in the latter part of 2008.[42] Grant Naylor Productions announced that it had been "on the cards" since February 2008.[43] It subsequently transpired that UKTV channel Dave will screen four new 30-minute specials to celebrate the twenty-first anniversary of the show.[44] The new episodes form part of an effort by Dave to screen more original programming, instead of just repeats.[45] The specials will be made up of a two-part episode (the 'one hour' Robert Llewellyn referred to originally), a "Making-of" the specials, and "a clip show with a serious difference".[46]
