I sometimes go onto
youtube and look up fan made "dream casts" for books. Some are really good! there was one from A Great and Terrible Beauty that totally made me want to read the whole series over again! The music was haunting. So pretty! I watched it again....

There are several for the vamp school series (House of Night and Vamp Acad) too...I think I"ve posted links to them in this thread... can't remember for sure though.
EDIT: I looked at the youtube for the uglies trailers and I SWEAR people cannot bear the idea of an actual "normal" looking person on screen! In other words, even the so-called ugly Tally is some gorgeous girl-starlette.

I want to see somebody REGULAR looking. It would make no sense to throw up some "pretty" girl and try to ugly duckling her with a make-over into ugly. I realize that "ugly" in the book wasn't necessarily ugly but it was supposed to be something OTHER than the socially acceptable version of magazine beauty (the magical proportion scale, etc), right??!! Sigh.....
And it's also funny how they use the same actors for the cast of each and every book that they're dreaming up dream casts for...
Anyway.. the other casts are more fun than the Uglies casting videos. lol
I don't know much about the politics of movies from books but I do know that most of the time I see a movie I had no idea (until possibly somebody mentions it to me) that the movie was a book to begin with! Obvious exceptions of course, but generally I don't know and I just go see the movie because it looks exciting. Uglies is a fun concept... the movie could be more popular than the book.

I've seen the series in the bookstores for a few years now.
I don't know how accurate this is but here is some info from IMDB.com
UGLIES
and interestingly enough, something about A Great and Terrible Beauty, too? This page actually lists a director and producer on board??
