10 Doctor Who Changes That Were Completely Justified

An Adventure in Space and Time is a wonderful one-off biopic that aired as part of the 50th anniversary celebrations.

Dramatising the story of the show’s creation through to Hartnell’s regeneration, it starred David Bradley as the main man, and was penned by Mark Gatiss (rather awkwardly blowing any of his actual Doctor Who scripts out the water). It’s a must-watch if you haven’t already.

The tear-jerker of a final scene sees Hartnell looking forward at what the show, at what his legacy, will become – at which point he sees Matt Smith standing across from him.

If you’re sticklers like we are, this scene is ever so slightly undercut by the fact that the green-screened Smith is standing in front of the console he’s clearly meant to be behind, completely taking you out of the moment. It’s a minor oversight, but fans have moaned about it for years.

Well, ten years later, An Adventure in Space and Time was broadcast again, but with one vital difference. The green screen mistake was fixed, and even better, it wasn’t Smith standing behind the console – it was in fact the first onscreen appearance of Ncuti Gatwa as the Fifteenth Doctor.

It was a powerful, powerful moment. No other show could do something like this, and the only downside is that we'll know what to expect with version three in a decade's time!
