Behind the Sofa (documentary series)

Behind the Sofa was a series of videos included in each release of Doctor Who: The Collection featuring cast and crew members from the show watching serials from the season the Bluray set encompasses.

Format
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 are produced for each individual serial, and have been included on each release of The Collection to date.
