Can you trust us?

Firstly, I need to state my enduring love for Maggie Smith in all her roles. My mom and I watched many of her performances together and she has always been a joint favorite. Secondly, I’m not sure which movie this is because apparently I’m not as much of a geek as I thought, so … Copyright JK Rowling and Warner Brothers. (Please don’t sue me, I love your movies and books and stuff.) Also apparently Prof. McGonagall’s classroom is one of the rooms off of the Durham Cathedral cloisters. I did peer through the lock because shut up, of course I did and …. yeah, confirmed.
