Spearhead from Space achieved many firsts for Doctor Who. It is the first Doctor Who story to be presented in color. And due to a strike at the BBC, it is the first Doctor Who story to be shot entirely on film. And now it becomes the first classic Doctor Who Blu-ray, made possible by scanning in the original film elements to create a stunning, true High Definition picture! As punishment for breaking the laws of time, the Time Lords have forced the Doctor to change his appearance, taken away his ability to time travel, and exiled him to Earth. But as the TARDIS arrives, so does a meteor shower carrying an alien invasion force.
