An animated version of Doctor Who's The Macra Terror has been released. The original 1967 version's video has been lost. This version recreates it with animation using the original audio. Does this version warrant it's own entry in the DB or should it be considered the same episode?

Originally broadcast from 11th March to 1st April 1967, and starring Patrick Troughton as the Second Doctor, Anneke Wills as Polly, Michael Craze as Ben, and Frazer Hines as Jamie, no full episodes of this serial are known to have survived on film. Fortunately, a complete audio recording of all four parts still exists. Now, 52 years later, the four episodes will be brought back to life through the power of animation in both colour and the original black and white, from 18th March 2019.
