<P> Mr. Mudd Productions (producers of Juno) became interested in the project and wanted Chbosky to adapt the film . The producers--John Malkovich, Lianne Halfon, and Russell Smith--hired Chbosky to write a screenplay adaptation (instead of Hughes) and to direct the film . Chbosky found value in half of Hughes' screenplay, so he negotiated for the rights from Hughes' heirs and added his own touches . In January 2011, Summit acquired distribution rights . The following month, Summit sought a buyer for the project at the European Film Market held simultaneously with the Berlin International Film Festival . </P> <P> In May 2010, actors Logan Lerman and Emma Watson were reported as in talks for the project and confirmed the following year . In April 2011, Mae Whitman signed on as Mary Elizabeth and Nina Dobrev was cast as Candace . Paul Rudd was cast as Mr Anderson later that month . On May 9, 2011, Kate Walsh announced that she was cast in the film as Charlie's mother and had begun filming . </P> <P> The film was shot in the Pittsburgh metropolitan area from May 9 to June 29, 2011 . Initial filming began in Pittsburgh's South Hills, including South Park, Upper St. Clair, and Peters Township High School . </P> <P> The Rocky Horror Picture Show scenes were filmed at The Hollywood Theater in Dormont after Chbosky learned that the theater was re-opening; he had seen The Rocky Horror Picture Show there when younger . </P>
