Jodie Whittaker has been announced as Doctor Who's 13th Time Lord - the first woman to be given the role.
Whittaker, 35, said it was "overwhelming, as a feminist" to become the next Doctor.
Whittaker said: "I'm beyond excited to begin this epic journey - with Chris and with every Whovian on this planet.
It means remembering everyone I used to be, while stepping forward to embrace everything the Doctor stands for: hope.
The actress also shares another Broadchurch link with Doctor Who - co-star David Tennant was the 10th Doctor.
Another tweeter, Ayad, said: "I don't even watch Doctor Who but a woman doctor is so cool.".
Traditionally, each Doctor has their own distinctive look, raising questions about the cloak Whittaker wears in the trailer. »
