Behind the Sofa (documentary series)

Behind the Sofa was a series of videos included in each release of The Collection Blu-ray sets featuring cast and crew members from the show watching serials from the correspondent season.

The series observes various members of the Doctor Who cast and crew - not always those limited to that specific season, and often cutting between different groups - watching a Doctor Who serial in full and reacting to it, similar to a DVD commentary track. Unlike a commentary track, however, the video is edited to feature specific moments and reactions, or cast/crew sharing specific anecdotes.

Behind the Sofa featurettes were produced for each individual serial, and have been included on each release of The Collection.

Behind the Scenes

 * The opening theme for the show segues into the Doctor Who theme, however the Doctor Who theme has been digitally slowed without reducing its pitch.
 * The Behind the Sofa segments included in the season 12 did not properly format the credit for Mark Ayres as Dubbing Mixer - while the credits otherwise presented the position in italics, "Dubbing Mixer" was presented in the same typeface formatting as the credited names. This error did not occur in later sets.
 * Season 12 is the only set where the BBC Worldwide logo appears in the end credits. From season 19 onwards, the credits end with the BBC Studios logo.
 * For the Season 24 and Season 8 installments, which were produced during the COVID-19 pandemic in 2020-21, guests were seated in their own individual chairs instead of on a sofa. There was also a plastic divider separating them.
