Filming started on series ten of Doctor Who today. But time-warping back to 1969, we were watching the end of the original season six. The Second Doctor was gurnned out of existence in the closing minutes of The War Games. In glorious black and white that Goth chap tells the Doctor his appearance will change. He’s a deadly assassin and the Doc will have to watch out for him.
A few weeks later Neil Armstrong and Buzz Aldrin would land on the Moon and some show called Star Trek would go Where No Man Has Gone Before. The Trek Doctor regenerated by the second episode.
