 We wanted to get away from the slightly flimsy look of the earlier series. So I beefed Davros up, made him more sturdy. I also think that the reinvented Davros is unusual for the new Doctor Who because he is genuinely grotesque. Sometimes we ’ ve held back a bit with the ugliness of the monsters. But Davros is a very unpleasant looking character, which makes his return all the more powerful.
