Doctor Who just started filming the current season on Monday, and Mark Williams, who plays Mr. Weasley in the Harry Potter movies, was in the scenes that were filmed. Now other Potter actors will also be guest starring.

It is unknown if he will be making an appearance in the same episode(s) that feature Mark Williams, but David Bradley, who Harry Potter fans know better as Mr. Filch, will be making his second Doctor Who appearance. According to Doctor Who TV:

Actors David Bradley and Rupert Graves are to guest star in Series 7 of Doctor Who…This isn’t actually Bradley’s first outing in the Whoniverse though; he was the voice of the vulture-like Shansheeth in The Sarah Jane Adventures story Death of the Doctor.

Rupert Graves meanwhile, will be recognisable to many readers as Detective Inspector Lestrade in Steven Moffat’s other show Sherlock.

What kind of character do you think these two actors should play?
