For the first series, producers were fearful of alienating new audiences with references to the original show, such as names and events, so such things were kept to a very bare minimum until audiences adjusted to the mythology. Even the first journey to another planet beyond Earth didn't take place until series two, which is unusual considering the universe-trotting nature of the original series.
Alex Kingston was born in 1963, the year the original series of "Doctor Who" first started.
Peter Davison has said he considers this series an improvement on the original, not only because of its budget and digital effects but also because the series is produced by a writer, unlike the original series, which was always produced by a BBC staff producer. Davison has said that Rose, played by Billie Piper, was the first properly developed companion in the history of the series, and he expressed admiration for the sexual frisson and tension which was previously disallowed between the Doctor and his companions.

At first the estate of Terry Nation refused permission for them to use Daleks in the show (Terry Nation held copyright over the Daleks). One of the reasons they refused permission was because of the BBC granting permission for the Daleks to be used in Looney Tunes: Back in Action (2003). Huge fan of Doctor Who Steve Martin, who was the one who insisted Daleks be used in the movie, heard about the news and wrote a letter of apology to the Terry Nation estate and upon receiving it, the Terry Nation estate granted permission.
In each series, there is an underlying story arc that pans all episodes until finally fully addressed in the season finale. For Series 1, it is the concept and identity of the Bad Wolf. Series 2, the Torchwood Institute. Series 3, the identity of Mr. Saxon. In series 4, there are several little references and jokes that eventually lead to the plot of the finale, including the missing planets and the bees disappearing from Earth, and repeated appearances of Rose Tyler on screens and monitors. In addition, there are repeated references to there being something on Donna's back. While this does not carry on to the series finale itself, it does play an important part in the episode which sets up the finale's story. In series 5, there are "cracks" in the universe, which must ultimately be fixed in the series finale. In series 6, a future version of the Doctor is seen to be killed, causing complications for the "present" version of the Doctor and his companions, also there is the repeated appearance of Madame Kovarian who only Amy can see. Series 7 revolves around the "impossible" Clara Oswin Oswald, whom the Doctor keeps running into in various places and times, though she does not remember him.
On Thursday 31 March 2005, the day after the show was picked up for a second series, the BBC Press Office announced that Christopher Eccleston was quitting the show, citing a fear of being typecast and long working hours as reasons for his departure. The BBC later apologized for issuing this statement, as they had done so without consultation with Eccleston. In fact it was agreed by mutual consent some months earlier that Eccleston would only do one series, with the BBC holding off announcing the news until after the series was finished. This would have allowed the regeneration of Eccleston's Ninth Doctor in episode 13 to be a surprise for the audience. Unfortunately, the BBC Press Office jumped the gun under pressure from the British Press who were concerned that a second series had been announced, but it had not been confirmed that Eccleston was returning. Fan reaction to Eccelston's departure was violent and the debate reached such a fever pitch that Outpost Gallifrey, the biggest Doctor Who fan site on the Internet, was forced to close down its forum for days.
