I love Alan Rickman. J.K. Rowling told him Snape’s entire background story before they filmed the first movie so that he would understand Snape’s character, now watching these movies a second or third+ time is so great, because then you see strange or subtle little things Snape does, facial expressions, odd glances, ect, and you can be like “Thats why he did that!”
