Christel Doctor Who of the Week...Minimal Earth visits in Series 4

I can officially confirm that series 4 of Christel Doctor Who will only visit earth a very small number of times. It has to be said that I am taking somewhat of a risk by doing this, especially considering that neither of the Doctor's companions will be directly from earth.

The reason for the lack of Terra planet fall is the new and exciting possibilities that Moviestorm brings and the chance to have the TARDIS crew visit an almost infinite number of planets and solar systems.
