Long before he embodied Severus Snape in Harry Potter, my tiny 6-year-old heart was majorly crushed and forever shaped by his portrayal of Colonel Brandon in Sense & Sensibility. (My family teased me about this for years.) (Also, one of our dogs may or may not be named Brandon because of it.) Alas, this dashes any hopes I might've had for one day seeing him cast as our beloved Magus, but he'll live on as such in my imagination.
I'm so very sad. What a legend. RIP, Alan Rickman. <3
