 Seriously , Davros is meant to be horrific , and we 've had so many withered geniuses in sci @-@ fi lately — like Emperor Palpatine in Star Wars — that I needed something to make everyone sit up and realise that this man is the King of Horror : the original and the best ! And he 's been through so many physical changes over the years , I wanted to add one of my own . I asked Louise to give him the new jacket buckles , because I wanted it to look like a straitjacket . It just seemed to fit , cos he 's so insane !
