It’s not helping me right now. Rather, there’s just so much to wade through, and I don’t think I’m using the right search terms.
I’m trying to get a sense of what children’s and young adult books have been optioned for movies in the next few years. What are the up-and-comers?
Also, what other fantasy movies, movies based on comic books, science fiction movies, etc. will be coming out in the next few years?
I’m just curious, because the trend seems to be more and more each year.
I can think of a few:

the Ramona books by Beverly Cleary
Bridge to Terabithia by Katherine Paterson, spring 2007
His Dark Materials–which has had perpetual director problems–by Philip Pullman
XFiles 2 is in talks
KITT2000 (Knight Rider! Yay!)
Wonder Woman/Joss Whedon
Shazam!
Eragon by Christopher Paolini
Inkheart by Cornelia Funke
The Wee Free Men by Terry Pratchett
Where the Wild Things Are by Maurice Sendak
Spiderwick Chronicles and Artemis Fowl (by 1. Holly Black and Tony DiTerlezzi, 2. Eoin Colfer)

Edited to add:

Meet the Robinsons, based on A Day With Wilbur Robinson, written and illustrated by William Joyce, set to be released by Disney in 2007
Dinosaur Bob, by William Joyce
A Wizard of Earthsea, by Ursula K. LeGuin, in production by Studio Ghibli (yay!) and due out sometime next year, as far as I can tell
Coraline, by Neil Gaiman, reported to be out next year sometime
the Alex Rider books, by Anthony Horowitz–first one due out in the U.S. near Labor Day, but to be released in the U.K. in July
The Dark is Rising, by Susan Cooper, allegedly coming out in December (but can’t find anything to back that rumor up)
apparently there’s also a new picture book named Punk Farm that’s supposed
to be made into a movie
Spider-Man 3
Superman Returns
Ghost Rider
A Scanner Darkly by Philip K. Dick
Cars
Pirates of the Caribbean 2 and 3
The Power of the Dark Crystal. Sequel, 2007. Directed by Genndy Tartakovsky.
Prince Caspian, summer 2008
7/26/06 ETA: Mel Gibson picks up Libba Bray’s A Great and Terrible Beauty

… what else? (I’m looking for stuff coming out, not ones that have already come out like Holes.) Also, I’m curious when they’ll come out, so I know when to expect them!
I’ll add to the main list as I get responses. I’ve also asked a “collective mind” aka child_lit for help. If you ever need booklists or any number of lists of other things, child_lit is amazing in its response. And they have great discussions of children’s literature, too. (It’s a listserv run out of Rutgers, or at least, the last time I checked it was, though they’ve had new servers sometime recently. Anyway, if looking for good children’s lit conversations, google “child_lit” and “Rutgers” and I’m sure you’ll find them.)
