10 Awesome Doctor Who Ideas That Nearly Happened

10. The Weeping Angel Fact Book

The Weeping Angels' first appearance after Blink revealed quite a bit more about the species than most fans expected, for better or worse.

However, one crucial element in The Time of Angels that went unexplained was the origin of the Weeping Angel book (described by River as "the definitive work on the Angels... written by a madman") that the Doctor flicks through.

Despite its importance, we never learn where this book came from, and that's because writer Steven Moffat removed an entire subplot about its origins.

He intended to reveal that the book had been written by one of Octavian's clerics. This cleric came on the mission we see in the episode, encountered an Angel, got zapped back in time, and then wrote the book, allowing the Doctor to access it in the future. However, this plot point was ultimately axed due to a lack of story space.

The Angels don't zap anyone back in time in this story, so it would've been cool to see a subplot revolving around that ability. And learning more about that book - one of the only known in-universe works about the Angels - would've been fascinating to boot.
