Doctor Who: 20 Things You Didn't Know About The Day Of The Doctor
13. The Story Was Almost Structured A LOT Differently
Steven Moffat isn't exactly known for his linear storytelling, and sure enough, The Day of the Doctor bounces between several different timelines, characters, and locations.
But the final layout of the episode took a lot of time to get right, with Moffat once considering introducing the three main Doctors in a completely different order.
An early version of the script started with John Hurt's War Doctor, before moving onto David Tennant's Tenth Doctor, and finally landing on Matt Smith's Eleventh Doctor.
In the end though, Moffat chose to start with Eleven - mainly because he was the star of the show at the time the episode aired.
