30. "Have A Good Life, Rose."
http://www.youtube.com/watch?v=xEuV_PGG9EU Another terribly sad moment of Doctor Who, and one of Christopher Eccleston's finest moments as an actor. There were doubts when he was cast as the Doctor, and calls that he was too cold in the role, but how could anyone argue that he wasn't a fantastic Doctor (no pun intended) after this scene? The tears roll down his face, Murray Gold's score wells up, and he tells her to move on. It's harder than telling her to let the TARDIS die. In a single scene, he communicates more emotion through a hologram than most actors could face to face with their leading actress. 29. Ten Faces The Sycorax
http://www.youtube.com/watch?v=i7oXxacwvhE We'd grown to love Nine. It had taken a while, but he was finally the Doctor. Excitable, smiling, and ready to run around the universe like he used to. But then Rose had to drink the heart of the TARDIS, didn't she? Ten was all but a bit useless in the first half of 'The Christmas Invasion', lying in bed for most of the episode. Until the battle with the Sycorax, when he really discovered who he was. And it was a performance that would go on to shape his role: hilarious, dark, unpredictable, always time for a chat with Rose, Harriet Jones and whoever... oh, and rude and not ginger. 28. The Caves of Androzani Cliffhanger
http://www.youtube.com/watch?v=JdLzNSV3bK4 It's one of the finest Who stories ever made, and this is perhaps the most dramatic ending to an episode ever. The Fifth Doctor would assemble teams of companions, and in The Caves of Androzani, he ultimately dies for Peri. The urgency, fear and bravery that Peter Davison portrays in the short space of a minute would be impressive enough, but bear in mind, he does it all strapped into a chair. A fantastic performance. 27. The Rings Of Akhaten Speech
http://www.youtube.com/watch?v=j2EV3bg_edA One of the defining scenes of Series 7, and Matt Smith's tenure as the Doctor, the speech from 'The Rings of Akhaten' may be his finest one so far. And what it makes it so brilliant is that we know what he's referencing. We've been there with him throughout all those battles, losses and victories, and in the fiftieth year of a show, it's a wonderful gift to hear him recall his life like that. But as the Doctor realises a minute later, the future's so much more exciting: the future's what the god needs to feed on. In a single scene, Neil Cross managed to surmise the past, and look to the future elegantly and eloquently: an apt episode for the anniversary year. 26. The Three Doctors Meet
http://www.youtube.com/watch?v=I6Uf4sjX8RE You always imagine that the Doctor would love to meet his other incarnations, and that two Doctors really would be better than one. But in The Three Doctors, Two and Three only succeeded to bicker like children. It's the wonderful playfulness we'd come to love from Troughton returning to face a sterner Third Doctor, threatened somewhat by his past self, and more than happy to face dangers alone. The episode only got better however when the First Doctor returned, deeming his successors "a dandy and a clown". It was a milestone for the show's history, not only for being ten years old, but for starting the multi-Doctor tradition.
