Hey, It's That Guy!: The three leads are fairly well-known on their own accord, but it can be disorienting to watch Harry Potter and the Goblet of Fire and then watch this film, given the presence of Gleeson, Fiennes, and Fleur Delacour's actress Clémence Poésy.

A Deleted Scene has a pre-Eleventh DoctorMatt Smith, as a younger Harry, decapitate a policeman named Potter. Or, to phrase it differently, "Harry, as The Doctor, kills Potter, years before he was Voldemort."
