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!
"Of course it is happening inside your head, Harry, but why on Earth should that mean that it is not real?" - Albus Dumbledore, _Harry Potter and the Deathly Hallows_ Make your dreams that are good a reality.
