Annapurna Pictures and Color Force have acquired the feature film rights to Maria Semple‘s best-selling novel Where’d You Go, Bernadette about the disappearance of a once-famous Los Angeles architect-turned recluse. Scott Neustadter and Michael H. Weber (500 Days Of Summer) will pen the screenplay. Semple will serve as executive producer along with Color Force’s Bryan Unkeless and Annapurna’s Ted Schipper. Jacobson and partner Brad Simpson will produce alongside Annapurna Pictures’ Megan Ellison. Told via letters, emails, texts and other documents, the novel tells the story of a brilliant but slightly unhinged woman who suddenly vanishes, leaving her Microsoft-guru husband and devoted 8th-grade daughter determined to find her. The film rights were negotiated by UTA and Anna Stein of Aitken Alexander for Semple. CAA negotiated on behalf of Neustadter and Weber, who are also represented by Kaplan/Perrone Entertainment and attorney Sean Marks of Myman Greenspan.
