20 Doctor Who Moments We'll NEVER Forget
2. The Curator (The Day Of The Doctor)
In an anniversary special full of unforgettable moments, the surprise return of Tom Baker takes the jelly baby.
What's sometimes forgotten is how brilliantly Jenna Coleman underplays Clara's delivering of the message that the Undergallery's Curator wants to speak to the Doctor. It would be easy to add some portent or mystery to those words, but she just throws them out as she heads back to the TARDIS.
And when Tom Baker's unmistakable voice booms out from off-camera, there are chills down everyone's spines, and goosebumps on their arms. It's a masterclass in set-up, which is hardly surprising given Steven Moffat's career as a sitcom writer.
What's more, it's the only instance of Tom Baker sharing the screen with another Doctor in official Doctor Who. Utterly magical.
