Behind the scenes
In the original script for The Dark Dimension, the story introduced a new type of Cyberman, the "Cybercommander". It's skeletal design has been commonly associated with the project. "'The Cybermen were not like any we've ever seen before,' says Rigelsford. 'There was a specific Cyberman who was being made by the people at Henson's Creature Workshop. The guy who designed it was Chris Fitzgerald . It had holes in its knuckles and there was a point where it held up its hand, made a fist, and six-inch blades shot out of its knuckles! It was like Wolverine out of the X-Men comics; Cyberrine!'"
