A new teaser for Series 11 of Doctor Who debuted Sunday during the World Cup, showing the newly regenerated Doctor as played by Jodie Whittaker as she whizzes by her three new companions.

And I do mean whizz, as she's portrayed as a ray of light that flashes by actors Tosin Cole, Mandip Gill and Bradley Walsh, leaving behind a hint that she just passed through.
