The recent "Dinosaurs on a Spaceship" episode of Doctor Who delighted viewers by mixing all kinds of incongruous things, from the titular example to the appearances of two beloved Harry Potter characters reincarnate in unexpected roles. Arthur Weasley (Mark Williams) and Argus Filch (David Bradley) appeared as Rory's father and a rather nasty space pirate, respectively.
What if more Harry Potter actors jumped aboard the Doctor Who space-wagon? Heck, why bother getting out of character?! Heck, why limit it to human characters?!
