I know it's exciting that The Tenth Planet is getting its fourth episode animated for the upcoming DVD release. However, please do not upload stills from that animation until the DVD is officially released.
It may seem counter-intuitive to suggest that such a thing could spoil a 47-year-old story, but remember that the animation is not from 1966 but 2013. So this is actually new Doctor Who — even to those few who were alive when that episode aired in 1966.
