Director Rachel Talalay recently wrapped initial filming on the upcoming Christmas Special, and she indicated that she had not filmed a scene with the new Doctor; more than that, she also made it clear that she had no official word to hand down as to their identity.
The one-minute long clip showed various famous landmarks from around the world, including Number 10 Downing Street in London, The Statue of Liberty in New York City, and more with the number 13 appearing repeatedly.
BBC revealed on Twitter that it will announce the identity of the 13th Doctor after the Wimbledon men's final. However, it is also met with the exact opposite reaction, as some fans were really hoping they wouldn't find out until they were watching the Christmas Special.
Currently, the betting odds look like they will go that way. Particularly with the Master, the Doctor's arch-enemy, turning into a woman named Missy several seasons ago.
Current favourites with the bookies include Kris Marshall and Phoebe Waller-Bridge.
Now leading the United Kingdom betting: Kris Marshall, best known to American audiences as the optimistic Brit who flies to the U.S.to find love in Love Actually.
Exciting news for Doctor Who fans!
The popular sci-fi series features a Time Lord, known only as The Doctor, who travels through time and space in the Tardis, which resembles a 1960s police telephone box.
