Doctor Who: 17 Cool Details Steven Moffat Just Revealed About The Eleventh Hour

17. The Show Originally Happened "In Amy's Head" (And The Opening Sequence Was Almost Different)

The episode opens with the TARDIS darting wildly over the London cityscape as the Doctor hangs out of its doors, clinging on for dear life. It's a very action-oriented and bombastic opening which, as Moffat tweeted, wasn't in the original script.

However, because David Tennant's final story had been such an epic one, Moffat (and executive producer Piers Wenger) decided that Matt Smith needed to start his tenure with a bit more of a big bang, and thus, the episode's pre-title sequence was born.

But what was planned originally? Well, Moffat revealed that the original script started with Amelia Pond's garden, before heading inside her house as she prayed to Santa. The camera then zoomed into her eye and transitioned to the titles, meaning that the whole show (or this individual series) would've taken place "in Amy's head".

Moffat is almost certainly being a little sarcastic with that last point, although the entirety of Series 5 being the dream of a young Amy Pond does sync up well with the idea that the Doctor is her imaginary friend, something that is actually brought up in this episode, and in later episodes.
