Britain's Royal Mail is marking the 50th anniversary of the science fiction show "Doctor Who" with a series of stamps featuring each of the 11 actors who have played the title role. Those featured include the present doctor, Matt Smith, as well as past Time Lords such as David Tennant and Christopher Eccleston. The series will also include a miniature sheet that brings together Second Class stamps featuring four of the doctor's iconic foes -- a Dalek, an Ood, a Weeping Angel and a Cyberman. The stamps honoring the cult British television series will be available beginning at the end of March. You can see the rest of the stamps at the Royal Mail's website.
