This release has two discs. On the first disc are the original four episodes
of this story. On the second disc is the special edition version with extra
scenes, new special effects and modern Dalek voices. All the new material meshes
seamlessly with the original material adding to the story without changing it.
The special edition is much more enthralling than the original.
Something for Doctor Who purists as well as fans of the modern Doctor Who
series.
