Honestly more excited about the supporting cast than the trio

Don't get me wrong the trio looks great and Hermione coming from Matilda is a really good sign, but what I'm most curious about is who they get for the adults. The films had basically the entire British acting establishment and it elevated the whole thing.

My most wanted is honestly Lupin. That role carried so much of the emotional weight in Prisoner of Azkaban and the movies just didn't have the time to really dig into the Marauders backstory. Whoever they cast is going to have to carry some really heavy scenes and make you feel the weight of like 15 years of grief in a few conversations. Thewlis was solid but even he felt underwritten.

Who's everyone most hoping they nail from the supporting cast?
