Model score first leading role… British model-turned-actress Cara Delevingne (‘Pan,’ ‘Tulip Fever,’ ‘Anna Karenina’) has entered into talks for the coveted female lead opposite Nat Wolff in the upcoming adaptation of John Green’s ‘Paper Towns.’ “Quentin Jacobsen has spent a lifetime loving the magnificently adventurous Margo Roth Spiegelman from afar. So when she cracks open a window and climbs back into his life-dressed like a ninja and summoning him for an ingenious campaign of revenge-he follows. After their all-nighter ends and a new day breaks, Q arrives at school to discover that Margo, always an enigma, has now become a mystery. But Q soon learns that there are clues-and they’re for him. Urged down a disconnected path, the closer he gets, the less Q sees of the girl he thought he knew.” Scott Neustadter and Michael H. Weber, who also adapted Green’s ‘The Fault in Our Stars,’ are writing the script with Jake Schreier (‘Robot & Frank’) attached to direct.
