 Eccleston stated in April 2004 that he did not believe his Doctor would be " as eccentric and as foppish as he was in some of his incarnations " . Russell T Davies characterised the character as a " stripped down " version of previous Doctors . Regarding the Ninth Doctor 's less eccentric character , Davies stated : " He travels in time and space , he 's got two hearts , he 's a Time Lord — that 's eccentric enough to be getting on with " . In contrast with previous Doctors , the Ninth Doctor speaks with a distinct Northern accent . Remarking on this aspect of his characterisation Eccleston states that the character " is a scientist and an intellectual , and a lot of people seem to think you can only be those things if you speak with received pronunciation which , of course , is rubbish . " In regards to the Doctor 's costume , consisting of a black leather jacket and jeans , the actor states , " I didn 't want the costume to be my performance " and that " I wanted any flamboyance and colour to come out of my acting . " Eccleston thought that as the Doctor he should show a " slight dark side " but also bring out a lighter side . Executive producer Julie Gardner observed that the Ninth Doctor gave Eccleston the chance to be " very intense but also frivolous as well . "
