The video shows the regenerations of each Doctor and David Tennant appears in three regeneration scenes as they include his non-regeneration scene from Journey's End.
As the regeneration from the Eighth Doctor (Paul McGann) to the Ninth Doctor (Christopher Eccleston) was not shown on screen, the BBC have cleverly used a clip of The War Doctor (John Hurt) too.
But we think the video needs updating now to include Peter Capaldi!
The video should play worldwide.
