9 Stars Of Fortitude You'll Know From Doctor Who
6. Michael Gambon
Who Is He: Henry Tyson, a wildlife photographer who only has weeks left to live and who questions why Fortitude's sheriff, Dan Anderssen (played by Game of Throne's Richard Dormer) is mysteriously always around when crimes happen.
Who He Was In Who: Kazran Sardick, the miserly subject of the Doctor's attempt to channel Charles Dickens's A Christmas Carol to alter the past and make him kinder so he will help save a crashing spaceship.
