Producer Lauren Shuler Donner first thought of a prequel based on the young X-Men during the production of "X2", and later producer Kinberg suggested to 20th Century Fox an adaptation of the comic-book series "". Singer signed on to direct the film in December 2009; however, in March 2010 it was announced that Singer would only be producing. Vaughn, who was previously attached to direct "X-Men: The Last Stand", became the director and co-wrote the final script with his writing partner, Jane Goldman. The film superseded a planned "X-Men Origins: Magneto" film, and the Writer's Guild of America arbitration credited "Magneto" writer Sheldon Turner for the film's story. Principal photography began in August 2010 in London, England, and ended in December. The film was released on June 3, 2011.
