Georgia Moffett, daughter of Peter Davison (I), who starred as the Doctor from 1982-1984, auditioned for the part of Rose. She later got the part of Jenny in the fourth series.
Christopher Eccleston, largely unfamiliar with Doctor Who because he was never a fan of the "Doctor Who" (1963), prepared for the role of the Doctor by watching the DVD of "The Talons of Weng-Chiang", a Tom Baker (I) adventure originally broadcast in 1977.
Special effects man Mike Tucker (III) who is responsible for the model work and director Graeme Harper are the only crewmembers to have worked on the original show.
SPOILER: On Thursday 31 March 2005, the day after the show was picked up for a second season, the BBC Press Office announced that Christopher Eccleston was quitting the series, 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 season, with the BBC holding off announcing the news until after the series was finished. This would have allowed the death of Eccleston's character 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 season 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.
On Saturday 5 March 2005 (some three weeks before its TV debut), a rough-cut version of episode one, "Rose" was leaked onto the Internet by an unnamed employee of a third-party contractor to CBC in Canada. The person responsible had their employment immediately terminated. The version is mostly similar to the broadcast version - the most notable difference is that instead of using Murray Gold's new version of the theme song, a remixed version of the original was used instead
Because of the varying technical and logistical demands of the 13 episodes of the first season, filming was broken into five production blocks. Episodes 1, 4 and 5 formed block one, and was filmed between July and September 2004. Block 2 comprised episodes 2 and 3, and was filmed between September and October 2004. Block 3 contained episodes 6 and 8 filmed between October and December. Block 4 was split into two sub blocks, 4A and 4B due to the large visual effects demands of episode 7 which on its own became block 4A, filmed between December 2004 and January 2005. Episodes 9 and 10 made up Block 4B, filmed from December through February 2005. Episodes 11-13 formed Block 5 filmed from February until March 2005.
Producer Russell T. Davies had Christopher Eccleston's name on a shortlist for the role of the Doctor but didn't really think that he would accept the role. Coincidentally, Davies soon received an email from Eccleston asking if he could audition for the part.
Colin Baker (I), the sixth actor to play the Doctor in the original series during the 1980s, said he was ecstatic on hearing that Christopher Eccleston was cast as the Doctor, as he feared it would be very easy to cast someone in the role who just would not suit the part.
Penelope Wilton, who played Harriet Jones in episodes "Aliens of London" and "World War Three" of "Doctor Who" (2005), was offered a part in the original "Doctor Who" (1963) series as Lady Pienforte in the episode "Silver Nemesis". The part was taken by Fiona Walker (I).
Tom Baker (I) and Colin Baker (I) were considered for guest parts.
When the first series was being made, television pirates were desperate to acquire the preview tapes. One of the people in the office had the idea of labeling the tapes with the anagram "Torchwood" rather than "Doctor Who", as a security measure to disguise the tapes when they were delivered from Cardiff to London. Writer Russell T. Davies liked this idea so much that it later inspired him to use it as a title when creating the spin-off series, "Torchwood" (2006).
A planned spin-off, "Rose Tyler: Earth Defence", was canceled during pre-production in August 2006, as Russell T. Davies realized that it would render the goodbye between The Doctor and Rose at the end of season 2 meaningless and would be one spin-off too many, after "Torchwood" (2006) and "Sarah Jane Adventures, The" (2007).
Several episodes begin with the exact same sequence: a view of the earth's moon, then panning towards earth followed by a fast zoom down to London. Episodes in which this opening was used include "Rose", "The Christmas Invasion", "Army of Ghosts" and "The Runaway Bride".
Despite quite a lot of new scenes being added to episodes in post production during the first season, all 13 episodes ran under the standard length of 45 minutes, so teaser trailers for the next week's episode were tacked on to bring the length up to standard. This has now become a staple of the series.
For the first season, producers were fearful of alienating new audiences with references to the original series, 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 season two, which is unusual considering the universe-trotting nature of the original series.
Except for obvious scenes, most of the location shots are done in Cardiff, Wales in place for London. The one show set in Cardiff, "The Unquiet Dead," was filmed in Swansea, mainly due to the fact that no buildings currently in Cardiff were built during that episode's time, 1869.
Russell T. Davies was sounded out to produce a revival of the series by the BBC One Controller of the time, Peter Salmon, in 1999. Although nothing came of this due to BBC Worldwide's desire to make a film version of the show, by late 2003 the new Controller of BBC One, Lorraine Heggessey, had persuaded Worldwide to surrender their film ambitions so that she could commission a new television version.
Christopher Eccleston is the third actor to play the ninth Doctor, and his ninth Doctor is the third version of the character. Rowan Atkinson played the ninth Doctor in the 1999 BBC Comic Relief charity spoof _Comic Relief: Doctor Who and the Curse of Fatal Death (1999) (V)_. Five years later, Richard E. Grant voiced a different ninth Doctor in the BBC web animation _"Doctor Who: Scream of the Shalka" (2003) (mini)_. Only Eccleston's ninth Doctor is "canon", or official.
The Ninth Doctor (Christopher Eccleston) is the only Doctor to never encounter the Master on-screen. Although the Master wasn't introduced until the Third Doctor (Jon Pertwee) stories, the First (Richard Hurndall--for the late William Hartnell) and Second (Patrick Troughton) Doctors have crossed paths with the Master in the 20th Anniversary special The Five Doctors.
The series is recorded on single camera video and then in post production it is 'filmised', a digital process designed to make it look like it was made on film.
On 29 October 2008, David Tennant (I) announced he was leaving Doctor Who after the 4 specials in 2009.
