Doctor Who writer Steven Moffat revealed some hints about what viewers can expect from the new Time Lord to Doctor Who TV. Moffat said he was "pretty certain" Capaldi would keep his accent and would be an "older, trickier and fiercer Doctor". As a guide, Moffat said fans can expect the 12th Doctor's first few episodes to be similar to Tom Baker's: "He's really quite difficult to take at the beginning".
