 During filming, Neil Gaiman felt guilty about what his script was  putting the actors and crew through, since most of the series was  shot in the tubes of London in cold and muddy conditions. During a  break in filming of the fight between Hunter and the Black Friar,  when Tanya Moodie had accidentally broken her spear over the  stuntmans head, Gaiman stood up in front of the cast and crew and  began apologizing for putting them through such an ordeal. Laura  Fraser, who plays Door told him she couldnt believe they were  actually getting to make a series like Neverwhere, indicating that  everyone was having much more fun than Gaiman realized.
