A reconstruction of the Mất tích episodes from the 1967 adventure "Evil of the Daleks", featuring the 2nd Doctor, Patrick Troughton, using the audio, the snippets of video still remaining, and set stills to make a video slideshow with the complete story.
All the Doctors in just under 4 minutes, but really, would it be half as impressive is I'd put "44 years in 3 phút 36 seconds." Don't forget to spot the slight Rose/Doctor hint, and the wonderfully ironic flash of Adric's hand at 1:13.
