Going strong in its 54th year, Doctor Who has regenerated itself in more ways than one.
The current Doctor, Peter Capaldi has announced his exit from the popular British sci-fi show this year, with the Christmas special marking his exit.
And his place will be taken by Jodie Whittaker, best known to audiences as Beth from the crime drama, Broadchurch.
The teaser, which was telecast at the end of the Wimbledon men's singles final, comes across as a great surprise - primarily because Whittaker is the first woman to take on the role of the adventurous time- and space-travelling Time Lord.
The announcement was welcomed with mixed responses from fans the world over - with many lauding the casting choice, and some others doing a poor job of masking prejudices about a female Time Lord-

Can't wait for a time when women who are good at their jobs are given jobs without it being called 'political correctness' #DoctorWho13— Tanya Reynolds (@TanyaLReynolds) July 16, 2017

Jodie Whittaker will be seen assuming the hallowed mantle, first taken on by William Hartnell in 1963, in the Christmas special episode of 2017.
