Neil Gaiman won an SFX award for Outstanding Screenwriting for his "Doctor Who" episode "The Doctor's Wife." He sent them this video acceptance speech.
Christopher Salmon created this animatic of Neil Gaiman's short story in an attempt to convince Gaiman to allow him to create an animated film version of the story. It worked. The fully-animated version is currently in production.
Even with Neil Gaiman singing this one, I still maintain that "Supercar," another Gerry Anderson show, had the best theme song of all time.
