Andrew Morgan, director of "Remembrance of the Daleks" and "Time and the Rani," had some choice words for the Times on August 14. "As the director most recently embroiled with the Daleks... I have some inside knowledge of their anatomy -in particular their means of propulsion. While castors are quite efficient on studio floors, I felt we were courting disaster when one of the 1988 locations for a major battle was to be a cobbled street near Waterloo. However, the designer produced some all-terrain Daleks equipped with wheelbarrow wheels. I was delighted with this solution until filming began and the Dalek "operators" experienced great difficulty in climbing inside. There was no room for their feet and the enlarged wheels. The Daleks were completely and very effectively immobilised. Thankfully I was much more successful in a later scene, when I managed to film them going upstairs." That should take care of any doubts that the Daleks are incapable of stair travel... although it certainly might present an out for the Doctor at a later date!
