Gillian Flynn, the author of the best selling novel and screenwriter of its movie adaptation, tells E! News she has thought about writing a followup. Even Charlize Theron pushed for Flynn to do it. “I’ll get her drunk tonight and make her sign a contract,” the Oscar winner said. Flynn said, “I think about it every once and awhile.” Gone Girl, released in June 2012, was No. 1 on the New York Times Hardcover Fiction Bestseller list for eight weeks. Rosamund Pike, who earned an Academy Award nomination for her work as wells as a Golden Globe nom, has said that she’d come back for a sequel but only if Flynn wrote the screenplay.
