* All footage taken from the original episodes (along with original audio)

8. Paul McGann - Christopher Eccleston: No official regeneration exists. (This video features a fanmade regeneration created by Mulett.)
* The Eighth Doctor's reason for regenerating is unknown.

9. Christopher Eccleston - David Tennant: The Parting Of The Ways (2005)
* The Ninth Doctor dies of cellular degeneration caused by absorbing the energies of the Time Vortex.

10. David Tennant - Matt Smith: The End Of Time, Part 2 (2010)
* The Tenth Doctor dies of radiation poisoning caused by the faulting power supply of the Immortality Gate.

TRIVIA:

* The Doctor can regenerate two more times for a total of 12 regenerations (and 13 incarnations of the Doctor) according to Doctor Who mythology.

* The Second Doctor was never seen to actually change into the Third, simply fading off into darkness at the end of 'The War Games' (1969) and then stumbling out of the TARDIS, already regenerated, at the start of 'Spearhead From Space' (1970). Both scenes are included in this video.

* Colin Baker declined to appear in his regeneration scene after being fired by the BBC, so the regeneration in 'Time And The Rani' (1987) features Sylvester McCoy in a blond wig regenerating into the Seventh Doctor.

* No official regeneration of Paul McGann into Christopher Eccleston exists. Nine years had passed between the 1996 TV movie & the 2005 series, and producer Russell T Davies felt that beginning the 2005 series with a regeneration would be too confusing for new viewers. (My thanks to Mulett for creating the McGann to Eccleston regeneration seen in this video.)

* In 'The Stolen Earth / Journey's End' (2008) the Tenth Doctor partially-regenerates after being shot by a Dalek, but aborts the regeneration by redirecting the energy to his severed hand. It has never been officially stated whether this used up a regeneration or not (See it in my video "Regeneration 2 - New Beginnings.")

* The BBC's Doctor Who FAQ suggests that now the Time Lords are gone, the Doctor may be able to circumvent the limit on regenerations; it says:
"Now that his people are gone, who knows? Time Lords used to have 13 lives."

* Intro/Outro Theme: Möbius by Floorten.

* The music over the McGann - Eccleston regeneration is called 'The Doctor's Theme (Pappenheim Remix)' by Murray Gold.'
