Alan Rickman aka Professor Snape from the Harry Potter movies! Professor Snape is my favorite character in the series and Alan Rickman was the perfect actor to play him! I absolutely positively love this quote from him!
I'd like to point out that Hermione stopped smiling 1 year before Harry and Ron did. She probably knew the danger long before them <--- I'd like to point out that Harry stopped smiling after year two and Hermoine smiled year three.
