People wanted me to do a CD-ROM of 'Hitchhiker's,' and I thought, 'No, no.' I didn't want to just sort of reverse-engineer yet another thing from a book I'd already written. I think that the digital media are interesting enough in their own right to be worth originating something in.
Hundreds of people who've never written before send in 'Dr. Who' scripts. They may have good ideas, but what they fail to realize is that writing for TV is incredibly complicated. They have no idea how difficult it is and what the financial commitment is.
