Elisabeth Sladen: Planet Of Evil

"I loved working at Ealing Studios because of the history that goes back there. Also, it was nice to go to a planet that was evil but that looked beautiful, with all these wonderful flowers and jungle tendrils and things. Because normally, anywhere I went, it was either a rubbish pit, a quarry, or a dust heap."

-Elisabeth Sladen, Doctor Who Magazine #250 probably referencing her experience on The Sontaran Experiment-
