18 actors who have travelled between the universes of Harry Potter and Doctor Who
From the halls of Hogwarts to the Tardis, you wouldn't believe how many marvellous muggles have appeared in both...
Bill Nighy
His fearsome Rufus Scrimegour wasn’t too keen on Harry, Ron and Hermione but Bill Nighy’s Doctor Who character was equally as critical. He made a brief but memorable 2010 cameo as Dr Black, an expert on Vincent van Gogh.
Jim Broadbent
He popped up as potions master Horace Slughorn, who told Harry all about Voldemort’s horcruxes in Half Blood Prince but did you know he was very nearly the Doctor? Well, sort of. Broadbent joined the likes of Rowan Atkinson to play a possible future version of the 8th Doctor in Comic Relief Special The Curse of Fatal Death
John Cleese
Nearly Headless Nick himself also popped up in Doctor Who, joining fellow Harry Potter star Julian Glover for a brief cameo in City of Death.
