10 Doctor Who Deleted Scenes That Would Have Changed Everything
8. This Is The BBC (The Keys Of Marinus)
First Doctor serial The Keys of Marinus isn't about our heroes being locked out of their houses, but rather a quest to restore a supercomputer. It also very nearly revealed a key part of the Doctor's origin story.
In an early version of the story, the Doctor revealed why he and granddaughter Susan were on Earth during the events of An Unearthly Child (the very first Doctor Who serial), and why he was in a bit of a grump during that time.
The TARDIS scanner was broken (typical) and it was only showing images in black and white. So, who does the Doctor turn to in his time of need? Why, the British Broadcasting Corporation, of course!
The Doctor was on Earth visiting the BBC, seeking help to fix the TARDIS scanner. He would, however, find them "infernally secretive". This is all kinds of meta, especially when you take into account that The Keys of Marinus is in black and white, not colour.
Revealing that the Doctor had visited the actual BBC would've been a bonkers idea, but this sequence was removed before filming. Probably for the best.
