Portland is where "Twilight," the first big-screen adaptation in the series based on Stephenie Meyer's vampire novels, was set.
A new production company, Sunswept Entertainment, has been brought on board for "Breaking Dawn," AB Media said in a release Monday. Sunswept Entertainment was created by Karen Rosenfelt, who is the daughter of former MGM chairman and chief executive officer Frank Edward Rosenfelt.
Karen Rosenfelt served as producer on "Twilight" and the third film in the series, "The Twilight Saga: Eclipse," which is set for release in 2010.
She did not work on "New Moon," which is due out in theaters next month.
"There will likely be quite a bit of tweaking to the fourth movie (adaptation of the) novel in the series due to the explicit sex and birth scenes to avoid an R rating," AB Media said. "Inside sources confirm that 'Breaking Dawn' may be filmed and released in two parts -- 'The Twilight Saga: Breaking Dawn Part I' and 'Part II.'"
Although this has not been confirmed officially by Summit, Meyer has said, "It would have to be made into multiple movies because it's hard to imagine it fitting into 90 minutes."
