I was oblivious toward Harry Potter when the film Goblet of Fire came out. I went to it on a date with a few other people, who were serious fans. We went to the first midnight showing, actually. They were generally displeased with Gambon's portrayal of Dumbledore, this after just one movie. Maybe they warmed up to him after more movies, I don't know, there wasn't a second date. But as such, he was my first Dumbledore. And later, when I read the books, not having seen any other film yet, I thought "yep, that actor was Dumbledore."
