In this episode Mark talks about one of his favourite TV shows that he has been watching since he was a child: the British science fiction television series "Doctor Who". First premiering on November 23, 1963, with its pilot episode "An Unearthly Child", the premise of the show revolves around the adventures of a rogue Time Lord who calls themselves "The Doctor" - who fled the planet of Gallifrey just prior to the start of the series using a stolen TARDIS (Time and Relative Dimension in Space) which allows its pilot to travel through space and time to anywhere in the universe: a time machine which has a vast interior, but which looks smaller on the outside - which, by using it's "chameleon circuit", allows the ship to disguise itself based on the surroundings it finds itself in but which continuously remains in a form based upon that of an early 20th Century blue British police box. "The Doctor" has remained a mysterious and enigmatic character throughout every incarnation of the TV series - and to this end, every time "The Doctor" regenerates - a physical transformation that occurs in Time Lord biology when they are near death - a brand new incarnation shows themselves and as a result a new actor takes on the role as the Time Lord. Currently their have been 13 different actors who have portrayed "The Doctor" - 12 male and 1 female - and the show in turn has had several different producers and writers who have contributed to the continuity and the narrative of the show and who have over the years fleshed out who "The Doctor" really is. "The Doctor" has had several different friends, assistants, and companions who have joined him on his adventures through time and space who always serve as the Time Lord's constant conscience, and who symbolise the viewers of the show who have watched the series and the title character literally change before their very eyes many times of the years.
