Hogwarts: This professor is too Muggle

It's the new school year. Hermione Granger, who returned to school after summer vacation, welcomed the Muggle Studies class she had been looking forward to. The enlightened Professor Lewynter showed movies in class, but these movies... seemed to be a little wrong.
Azkaban Redemption
Sirius Black: You know some dogs are not meant to be caged, freedom shines in every strand of their fur.
Infernal Affairs
Wormtail: You undercover guys are really interesting, always meeting in the cemetery.
Snape: I'm not like you, I'm honest.
Wormtail: Give me a chance.
Snape: How can I give you a chance?
Wormtail: I had no choice before, now I want to be a good person.
Snape: Okay, tell Mad-Eye and see if he tells you to be a good person.
Wormtail: That means my death.
Snape: Excuse me, I'm from the Order of the Phoenix.
Wormtail: Who would believe that?
Memento
Bertha Jorkins: Someone has been messing with my memory. At first I just forgot the afternoon, then I started to lose track of dates and what I had for breakfast…
I wanted to visit my aunt in Albania before I lost all memory of her, and Mr. Crouch was very considerate in granting me this leave.
Crouch?
I seem to remember something, a great secret.
Danger is approaching.
right now,
who am I?
Where am i?
