Sir Snape? 

It should be Sir Severus. "Sir" as a title is always followed by the first name. Or Sir Alan in that case. But I'd prefer him to get a Oscar, really.

It would be good to see Alan knighted but (If I remember well) he said that he dislikes the Queen and that kind of stuff, so..

Thanks, LadyNottingham, I know that already, I just thought Sir Snape sounded catchy...

Just out of curiosity, and because I don't know much about knighthoods or anything......how does merely acting in some movies, no matter how good you are, warrant a knighthood? I thought that was just for heroic actions and such?

^Not any more. I know a few actors/actresses who've been knighted. (Maggie Smith, for example.) According to link people are now knighted for making "significant contributions to national life. Recipients today range from actors to scientists, and from school head teachers to industrialists. "

Ohh, okay. But how is making good movies a huge contribution? Yes, it's awesome entertainment, but still.....

He also supports a number of charities, he just doesn't publicise it as much as other celebrities do.

@Kate: I'm not sure why actors (and some of the other occupations) can be knighted. That's a question for a fan who lives in the UK. I just know that actors can be knighted.

Since I live in the UK I'll explain. Knights from centuries ago became knights for chivalry, and doing good deeds. Except a lot of people these days aren't particularly chivalrous, so nowadays people are knighted for outstanding contributions to things...so Alan Rickman has contributed to the movie industry and our entertainment.

^That makes sense, I suppose.
