No, just time. My ideas evolve every day. What I'd have done 5 years ago v different from 10 years ago and that's v different from 5 years before. It's got to feel fresh and current and what I want to see from a character now. I'd jettison lots of stuff that's been covered in other books and movies. The take I have at the moment is very, very different from what we've seen in three quarters of a century, but very in-keeping.
