Russell T Davies wanted crowds of them for the new series opener Partners In Crime. Who are you going to call? Oscar winning Stephen Regelous, creator of massive software, which conjured up the vast battles in the Lord of the Rings films, that’s who. Trouble is, he lives in New Zealand. But, adds Cohen, as Regelous is a huge Who fan, he said “If we ever needed to do a crowd for doctor who, he’d come here and work for us” And he did. The Image at the side shows and adipose and the instructions that govern its movement on massive software. “We made two versions of the adipose: background extras, which have artificial intelligence and can move independently; and “hero” ones in the foreground which the Mill animated.”

The Mill love them and Cohen sees extra potential: “Someone made a stress-busting toy out of them. I have one at my desk at the moment!”
