So, are you going to make all of the Twilight movies, or just the two? I think that you should make all the movies.
All of the books will be made into movies. "Twilight" was already released in theaters and subsequently on DVD, and "New Moon" is slated to be released in theaters on November 20, 2009 (not long to wait now!). The third film, "Eclipse" is slated for June 30, 2010. The fourth book, "Breaking Dawn" is still in preproduction, and there are rumors circulating that the book will be broken into two movies because of it's length (this may have been started because of a comment made by Stephenie Meyer about her preference that the book be split into two movies). Summit has not announced anything regarding the fourth book/movie(s) yet, except to say that filming is expected to begin in Spring of 2010. We can expect the series to conclude on film sometime in 2011.
Well there has actually been 5 movies that have been made. Twilight, New Moon, Eclipse, and Breaking Dawn Pt. 1 and Pt. 2. The whole series has finished based on those 5 movies.
Since Twilight was a huge success they decided to make New Moon into a film as well and were met with a great response that was likened to the first movie. So then the entire series of Twilight was then signed on to be recreated into movies. However Breaking Dawn has two parts.
