Christopher Eccleston set the stage of incorporating more diversity in the Doctor Who reboot being from the northern part of the United Kingdom. This was extremely diverse for the UK because everyone is to try to be posh and speak like the Queen does because that gives them status both economically and socially. Otherwise the Doctor is still a white British male who isn’t ginger yet. Though the Ninth Doctor didn’t seem to bring anything back from previous versions he rather built a new persona. The only thing he brought back was his know it all attitude that he carried otherwise the clothing was ‘normal’ for the Doctor. Nine was very rebellious and seemed to be trying to move on from any connection to his past.
David Tennant being Scottish brought an even broader audience because he is a more popular actor who brought more viewers. Though still not ginger the Tenth Doctor brought a new style of acting and clothing. Ten went back to an odd outfit with a suit, long coat, and converse but it is still not as out there as a long scarf or a celery stalk. He did however, bring back a lot of the fifth Doctor with the glasses and they each dash around but appreciate beauty in the things around them. They each also stand with their hands in their pockets in tense situations which gives a casual appearance. Ten also aligned with the First Doctor in his final days by becoming selfish and trying to avoid regeneration and moving on.
Matt Smith brought a youthful feel being the youngest Doctor ever cast. This many would say is an age chosen by the Doctor to hide an old weary soul. Smith portrays the Doctor a lot like the second Doctor because he is goofy, can be physically awkward, and his love of hats. This Smith has credited to being that the Second Doctor was the Doctor of the stories he watched after being cast due to not having Doctor Who while growing up. Eleven also kept a suit but had sand boots instead of converse and later adopted spectacles for a few episodes to go with Five and Ten. Smith when cast as the Doctor wasn’t well known but this role brought him to fame.
Peter Capaldi again being Scottish brought some variety to the Doctor. Capaldi is the oldest doctor cast other than John Hurt who only has appeared a few times playing the War Doctor. The show did play some on Capaldi being from Glasgow with Clara making a few jokes here and there. Twelve being older than his two previous incarnations showed that he is accepting the maturity that he showed in his earliest incarnations. In season eight Twelve had a style that reflected the Third Doctor with a look almost of a magician. And in season nine he adopts a ‘disheveled “cosmic hobo”’ look like the Second Doctor. However, he shares a lot of traits with the Third Doctor like the love of invention and a sense of flamboyance with dramatic pointing or poses.
Jodi Whittaker being female also brings another sense of diversity into the Doctors incarnations. However, she is still white so maybe the 14th Doctor will be a person of color. In her outfit, she adopts the stripes of the Fourth Doctor on her shirt, the long coat of the Tenth and Fourth Doctor, the boots and suspenders of the Eleventh Doctor, and high waisted trousers like the Second Doctor. So overall most of her look comes from previous incarnations. But still not ginger! So, we will see where the Thirteenth Doctor takes us and how she acts compared to her previous incarnations.
