The CompanionShow to ''Series/DoctorWho'', with a behind-the-scenes look at the making of the show. It has aired since the show was brought back in 2005 until the end of the sixth series in 2011.
In the UK, it aired on the digital channel [[Creator/TheBBC BBC Three]] immediately, or soon, after ''Doctor Who''. [[NoExportForYou Everywhere else in the world is lucky if they get to see it at all.]] Notoriously, the DVDBonusContent has only "Confidential Cut-Downs" - hacked up episodes, reducing the original 45-minute exploration of the latest episode to 10 minutes (due to a mixture of licensing issues often relating to episode footage and music, and the logistics of releasing a series of equal length to the original series, thereby doubling the cost of producing already-expensive DVD and Blu-ray sets). This strategy is also used for repeats of ''Confidential'' episodes, so you need to catch it when it airs or KeepCirculatingTheTapes.
When it first aired, it used a lot of clips from the BBC's ''Doctor Who'' archives (well, the bits they haven't [[MissingEpisode wiped]]). Later, it was a mix of being a ClipShow version of the episode you just watched and talking heads [[GushingAboutShowsYouLike gushing about the show]], [[GushingAboutCharactersYouLike the characters]], [[GushingAboutWritingYouLike the writing]], and how amazing it all is. However, as the writers were often talking here, it was fertile ground for listening to the WordOfGod, or a frustratingly enigmatic ShrugOfGod at least. Arguably the most popular aspects of the series were those episodes that showed the actors having fun behind the scenes, or the producers did something different, like allowing David Tennant to host and direct one episode and having Karen Gillan and Arthur Darvill live out their personal fantasies in another. Occasional episodes also provided glimpses at bloopers and other outtakes.
In the United States, Creator/SciFiChannel [[NoExportForYou never imported the show]], but when the show moved entirely over to BBC America, 2-minute segments from the corresponding ''Confidential'' episode and played during one of the commercial breaks during episodes of Series 5. When PBS began airing the revived series, many stations also began airing ''Doctor Who Confidential'' alongside.
Although criticized by some, ''Doctor Who Confidential'' (alongside the masses of documentaries produced for classic-series episodes) helped make ''Doctor Who'' the most-covered TV series ever and led to its own spin-offs ''Totally Doctor Who'' (a series aimed at kids) and ''Torchwood Declassified'', as well as inspiring other series such as ''Merlin'' to do their own. In 2012, although the series is officially cancelled, it was announced the ''Confidential'' production team was producing behind-the-scenes material for the BBC's Doctor Who website.
