Hmm, my only objection to Rory Kinnear is that he looks so solidily human am finding it hard to picture him as other. But, perhaps that is just because Matt does that so well.
If after bluff and double bluff there is a female doctor, I really hope it is the alien aspect of the doctor that is brought out; a female who is a bit odd, intellectual and bemused by popular culture. That’s a role model I could have identified with in the 80’s, would have been an improvement on Lisa Simpson anyhow.
