â€œWho is he?â€ we hear you ask! Well to be frank, we have no idea either but if the producers of Doctor Who want him to star then he must be doing something right to grab their attention. Katherineâ€™s Twitter update read as:
“Pls follow my friend @dannyhorn who is also in the Doctor Who Xmas Special. Tho we can’t tell you what he does/is or we’ll have to kill you!”
The mystery deepens. Will Danny have a large role or will this be a Mike Skinner-style cameo when the singer appeared in The Time of Angels for 8 seconds?
