10 Unnecessary Doctor Who Details You Need To Know

10. Doctor Who Double-Decker (In The Forest Of The Night)

Doctor Who seems to have a thing for planting easter eggs on red London buses.

Planet of the Dead’s bus featured an advert for a company owned by Joshua Naismith, who would go on to appear in The End of Time. But that example is nowhere near as audacious as the double-decker featured in Series 8’s In the Forest of the Night, which seemed to be advertising Doctor Who itself.

The bus in question appears very briefly towards the start of the episode. If you look very closely at the poster emblazoned on its side, you should be able to make out the now-iconic Series 8 Twelfth Doctor costume reveal pic, together with a shot of Clara from Hide, and a generic photo of the TARDIS.

And it gets weirder. This wasn’t something cobbled together by the production team, but a piece of fan art made in anticipation of Series 8, which can still be viewed online.

It’s not clear quite how, or why, this happened – both from a behind-the-scenes and in-universe perspective. But however you square it, you can’t deny that it’s a rather intriguing detail.
