“Wyck Godfrey, the producer of all the films in the “Twilight” saga, admits that the creative team still doesn’t know how they’ll handle the character [Renesmee] in the “Breaking Dawn” movie, but said that the plan is absolutely for the production to go forward — as either one or two installments — with an eye toward beginning to shoot in Vancouver this fall. All three stars are signed for “Breaking Dawn,” he said, meaning that Stewart and Pattinson will be dealing with the joys and woes of interspecies parenting and newly minted heartthrob Taylor Lautner will return as often-shirtless shape-shifter Jacob Black.
At the moment, screenwriter Melissa Rosenberg, who’s penned all the “Twilight” movies, is working on the “Breaking Dawn” script(s). “It’s a work in process,” Godfrey said in an interview Friday. “The issue [of whether there will be one or two movies] is not going to be resolved until we get the full treatment and see whether it’s organic. If it’s not organic, I don’t think it will be done, and if it is, it will be. It really has to do with how much level of detail from the books there is, with all of these new vampires that appear in ‘Breaking Dawn,’ the whole section about Jacob… It’s a very long single movie if it does become a single movie.” i found this on internet
