Doctor Who has been going for over 60 years by this point, and the constant churn for story ideas in the early days meant that all manner of good and bad ideas have been tossed aside As Doctor Who fans, we often love to ponder these might-have-beens.

How would Christopher Eccleston have interacted with Matt Smith and David Tennant? The mind boggles with the possibilities of some of Doctor Who's greatest missed opportunities. However, the mind recoils at the mention of some of the terrible ideas that almost made into televised Doctor Who.

An unmade Doctor Who episode where Sarah Jane Smith was murdered by aliens? No thank you. A Christmas special in which JK Rowling's imagination comes to life? Absolutely not.
