I’ll tell you Insane Jedi Girl…after Movie III, I’ve felt that Lupin(who was & remains my fav. Defense Against The Dark Arts teacher) has been seriously underused. He seems to just be given a role where all he has to do is stand & look worried. I wanted to see more play between him & Tonks. I haven’t read any of the books…but that scene sounds incredible. David Thewlis brought up to life so well in Prizoner of Azkaban, and he emerged as more than a mentor to Harry to me…as well as being such a conflicted character because of his affliction…which they haven’t delt with at all in subsequent movies.
