She's back. The Thirteenth Doctor is returning for the thirteenth series in what is set to be a six-part Event Serial. Since their last epic battle in "Revolution of the Daleks," the Doctor (Jodie Whittaker) and Yaz (Mandip Gill) have been exploring the universe together but with the Doctor now questioning everything about her past there, she will undoubtedly be searching for answers. This adrenalin-fueled; universe-spanning series will also see an addition to the TARDIS with actor and comedian John Bishop joining the cast as Dan Lewis who will quickly learn there's more to the Universe than he could ever believe. Jacob Anderson ("Game of Thrones," "Broadchurch") is also set to make his debut on Doctor Who as reoccurring character Vinder. Jacob's new role will see him join forces with the Doctor, Yaz, and Dan as the Doctor faces her biggest ever adventure.
