To address one of the minor points of the first post; I actually didn't much like Richard Harris as Dumbledore at all. Oh, he looked right, but he didn't act at all like Dumbledore, nor did he sound like Dumbledore, nor did he have the personality of Dumbledore. The Dumbledore I had read in the books was not this somnambulent whisperer. Gambon (his first name escapes me at the moment) seems to have actually read the books and understood Dumebledore, which makes him a step above Richard Harris's portrayal, IMO. Although I will admit that he didn't much look like Dumbledore to me.
