The Doctor (Doctor Who)
The Doctor is the title character in the long-running BBC science fiction television programme "Doctor Who". Since the show's inception in 1963, the character has been portrayed by thirteen lead actors. In the programme, "the Doctor" is the alias assumed by a centuries-old alien—a Time Lord from the planet Gallifrey—who travels through space and time in the TARDIS, frequently with companions. The transition to each succeeding actor is explained within the show's narrative through the plot device of "regeneration", a biological function of the Time Lord race that allows a change of cellular structure and appearance with recovery following a potentially fatal injury.

Many serials from the classic era have been released in box sets:Other box sets have been released repackaging previously released serials (often with a recently released one):A series of three box sets released between 2010 and 2012, containing new editions of previously released stories with new restoration and special features.For the revived era, in addition to full series box sets, and the box set of the 2009 specials, the following collections have been released.Several box sets have been released in multiple editions, some with different outer cases but the same content.Some sets have been released compiling stories and episodes from both the classic and revived series:The original release of "The Five Doctors" was the very first Doctor Who DVD release, and as such, is rather lacking compared to later releases in the range. This release contains a straight transfer of the 1995 Special Edition, which recut the story, added several scenes, and replaced the original effects with CGI. The Region 2 version had no commentary track, but one with Peter Davison and writer Terrance Dicks was added for the Region 1 release nearly two years later. The Doctor Who Restoration Team has repeatedly stated that neither they nor 2 Entertain considers this to be part of the "official" release range. The packaging for the DVD and the design of the menus is different from all other releases in the range, although the BBC have subsequently made a new sleeve available for download from the official Doctor Who website which is intended to better match the rest of the range. A new version of the story was released in Region 2 on 3 March 2008, containing remastered versions of both the special edition and the story as originally transmitted. It also features both the R1 commentary track, a newly recorded commentary, and a number of special features. To distinguish it from the previous release, the newer version is subtitled "25th Anniversary Edition".
