"Doctor Who" 50th anniversary "Day of the Doctor" photos revealed The first photos for "The Day of the Doctor" are out, offering a glimpse of the highly anticipated "Doctor Who" 50th anniversary special. The images (check them out in the gallery above) feature outgoing "Doctor Who" star Matt Smith (who plays the 11th incarnation of the Doctor), along with his popular predecessor David Tennant (the 10th Doctor) and newcomer John Hurt. Hurt was introduced as the Doctor in May's season finale, though fan speculation abounds as to whether Hurt's character is a previous iteration, a future iteration or an alternate-timeline version of the time traveler, or else another character altogether. The special also stars Jenna Coleman, who plays the Doctor's current traveling companion Clara Oswald, and Billie Piper, who portrayed fan-favorite traveling companion Rose Tyler, the first female lead after the show's 2005 reboot. The newly released images from the episode also include a peak at Jemma Redgrave as Kate Stewart - a character first introduced in a 1995 direct-to-video story "Downtime." She appeared in last season's episode "The Power of Three," in which she served as the head of scientific research at UNIT. The 75-minute "The Day of the Doctor" is slated to air Nov. 23. In an effort to avoid spoilers and plot leaks, BBC Worldwide is orchestrating a worldwide simulcast in 75 countries, including the U.S. The special marks Smith's penultimate appearance as the Doctor after he announced earlier this year that he is leaving the show following the Christmas special. Scottish actor Peter Capaldi has been named as Smith's successor. "Doctor Who" casting: Moffat says "You know it when you see it" Peter Capaldi: A return to distinguished tradition?
