I'd really, really recommend reading the HP books before attempting fic.
I'm sure. And actually, I've read the first three, maybe even four. But I read them rather quickly, because I didn't like them much, and I wasn't on the look out for slash possiblities. And now, I've forgotten most of them, but have convinced myself that HP is the fandom that's best, because of my two slashers to put in, that's the only one they're both in. Which is not a way to go about producing the best slash. I'm going to give up fairly soon and write Buffyverse or Star Wars if HP really doesn't work.
I feel I should give it a try, that's all.
Here is an interesting idea, that occurred to me.
Is there a difference between HP movief fanfic and HP book fanfic?
It's a good question: how different are the canons? I've seen the movie more recently- but when I've got to write futurefic, not really that big a help. I suppose if I call it movie canon, any mistakes I make out of ignorance can be put down to the....
I should try and find a way to bring Harry and Snape to Sunnydale, and slash them there, shouldn't I?
Is there a difference between HP movief fanfic and HP book fanfic?
I don't think so, not really. The difference might be seen in visualizations of the characters. Rickman is older than Snape is, canonically.
In fact, if anything, the movies fail from being too slavishly faithful to the books.
I've read that the movies were as literal adaptations of the books as possible because the producers felt that was what kids wanted.
As a kid, I would have been seriously peeved by anything that
wasn't
a blow-by-blow adaptation of the book. I feel that the way Peter Jackson & Co. edited, adapted, and shuffled LotR was close to perfect. It acknowledged that film and book are two completely different media with different strengths
and
weaknesses.
Shrug. Maybe it is what they wanted. Maybe it's what they want not knowing what the alternative is. (I mean, there are plenty of grumbly Tolkein geeks out there, but having re-read FOTR since seeing the movie, I'll admit that Jackson's a better storyteller than JRR was.) For me, though, the combination of the extremely literal adaptation and Chris Columbus's plodding directorial style made the movies into very lovely, very well-acted snores.
Kids are incredibly picky. I know when I was a kid and I used to see adaptations of books I'd read over and over and over I would freak out "That's not how it goes. That's not right. They left that out. This is WRONG!"
And I think it comes down to the decision of who they wanted to please more with the Harry Potter movies---the kids who wanted to see everything as close to the book as humanly possible or the adults who wanted to see the best adaptation, even if that meant making more changes to the movie.
