Certainly when we watched them on set they felt very creepy and the redesign of the masks recalls to a certain extent some of the earlier ‘Moonbase’/‘Tomb Of The Cybermen’ designs. What Neil Gaiman’s also done in that episode is actually used the notion of being able to write a story about the Doctor in conflict with the Cybermen in a new way, to really make it a huge episode for Matt. It’s a brilliant performance, that one.
