I definitely like the way that this forum's answers and conversation has grown immensely more mature from page to page ;-)
I think i read only one other person mentioning that Warbreaker would also make a good movie- It's magic system is very visual, and all sorts of things could "show" well.
I'm also on the cautious bandwagon due to what has been repeatedly said about book to movie adaptations. what helped me explain things like the Harry Potter series- is that by itself to those who had never read any of the books, the movies did a good job telling a story while including as much as possible of the source material- towards the end, I saw the movies as more "companions" to the book- where the film was able to expand on a lot of aspects of the book... I personally enjoy the movies and books themselves.
On another hand one that i didn't see mentioned here book to movie adaptation, was "Jumper". I know a lot of people didn't really care much for Hayden's acting, but- as far as the movie goes, i liked it a lot- so much so, that I ended up reading all of the jumper-series books by Steven Gould. (4-5 at last count? its been a little while). As far as source material from books to movie- very little was actually there. the basic premise was there as in there was a dude named David, he could teleport, and people were after him. Aside from that, the movie went on a completely different tangent than the books. Having watched the film first, then read the books later- i think i liked the entire aspect a lot more. For me, it wasn't necessarily a matter of "the movie didn't follow the book at all", but more a matter of "a different story" in a "world" that i enjoyed. instead of getting one book to one movie, i got an additional separate story out of it all too. For me, the two are near separate, but related enough that i can imagine it being just an alternate story in the same world that i enjoy.
Now regarding Brandon's works- obviously I'm a fan of the books enough to troll these forums on a near daily basis... lurking in the background not ever really speaking up too much, but there anyway... so i really like the idea of a movie- even if it means getting some of the main points correct, and still being a really good movie. it could just be another "story" or a different "telling" of the same story. i think it helps knowing that Brandon'll be a producer and as Argent said before about how Brandon not some cash-seeking-new-writer just trying to make a quick buck... helps a lot. knowing his hand'll be in it helps me think that even if for cinematic purposes the story is only 20-30% true to the source stories, but they're *quality movies*, i'll win anyway. i get to get more of the cosmere in a different story.
