New Moon (marketed as The Twilight Saga: New Moon, and also known as Twilight 2) is an upcoming 2009 United States romantic fantasy film scheduled for release on November 20, 2009. It is based on the novel of the same name by Stephenie Meyer and is the sequel to 2008's Twilight, which is based on Meyer's previous novel. Directed by Chris Weitz, the film stars Kristen Stewart, Robert Pattinson, and Taylor Lautner, reprising their roles as Bella Swan, Edward Cullen, and Jacob Black, respectively. Melissa Rosenberg returns as the screenwriter for the film. She handed in a draft of the film script during the opening weekend of Twilight. Summit Entertainment greenlit the sequel in late November 2008, following the early success of Twilight.

In early November 2008, Summit announced that they had obtained the rights to the remaining books in Stephenie Meyer's Twilight series: New Moon, Eclipse, and Breaking Dawn. On November 22, 2008, one day after the theatrical release of Twilight, Summit confirmed that they would begin working on New Moon. "I don't think any other author has had a more positive experience with the makers of her movie adaptation than I have had with Summit Entertainment," said Meyer. Melissa Rosenberg had been working on adapting the novel prior to Twilight's release and handed in the draft for New Moon during Twilight's opening weekend in November 2008. The extraordinary world that Stephenie has created has millions of fans, and it will be my duty to protect on their behalf the characters, themes and story they love. This is not a task to be taken lightly, and I will put every effort into realizing a beautiful film to stand alongside a beautiful book —Chris Weitz, director of New Moon

In early December 2008, it was announced that Twilight director Catherine Hardwicke would not be returning to direct the sequel. Hardwicke cited time restrictions as the reason behind her leaving the project. On December 13, 2008, it was announced that Chris Weitz, director of The Golden Compass and co-director of American Pie, had been hired to direct New Moon.
