10 Doctor Who Easter Eggs Hidden In Plain Sight

Picking just one easter egg from the Day of the Doctor is a difficult task. With so many moments crammed into the special that honour the entire history of the show, which is best suited for a list like this one? Having said that, with the exception of the return of the Hartnell-era opening credits, there is one moment that shines bright.

While stuck in a cell, the Three Doctors ruminate on what happened to, and what will happen to, Gallifrey. John Hurt's War Doctor asks his older selves if they ever counted the number of children that had been on the planet on the last day of the war, which leads to a sad scene in which Ten forcefully says the amount while Eleven claims to have forgotten.

While this is happening, Eleven is hard at work on their escape. He is carving the code for a vortex manipulator into the wall, something Clara is able to use in the future to come back to the past - it's all a little confusing! However, that code has a very significant importance to Doctor Who - 22/11/63 is the date that the very first episode of the show aired, An Unearthly Child. Added to this, near the beginning of the episode, Clara passes a clock that is set to the exact time that the episode aired, 17.16.
