I hadn't really thought about that. I think the thing I've been thinking most about is how we're going to either make it similar to or different from the original unbroadcast story. I don't know whether we shall be exploring Skagra's silver cape costume in any detail. I don't think that was Douglas Adams, that must have been the costume [department].

I'm sure if there are any kind of references they will be in the script, which Gary will very cunningly place in there, I imagine.
