This is a reconstruction of Episode 1 of The Daleks' Master Plan produced by Harold Achatz in 1997. This was included on the release of The Invasion reconstruction created by Michael Palmer which also featured a version of Mission to the Unknown from Michael Palmer too. Although I have posted what appears to be the same reconstruction on this link http://www.dailymotion.com/video/x6g56jc the video you are currently watching contains the original audio that was used when this episode was released over twenty years ago. I have done this so you can see the difference between the two and make a decision about which one you would prefer to watch.
I hope you enjoy this reconstruction which in my opinion was a very revolutionary attempt at bringing the first episode of a twelve-part Dalek epic to life.
