Mystery novelist Harlan Coben, whose “Tell No One” was a hit at the box office, will receive another Gallic adaptation with “Long Lost,” with the pic to be shot in English this time. French producer-distrib Gaumont has acquired rights to the France-set novel centered on a sports agent who stumbles on a terrorist plot while racing to find the long-lost daughter of an ex-girlfriend.Gaumont will develop and produce the adaptation with Nick Wechsler, producer of “The Road” and “We Own the Night.” At the Berlin Film Festival, Gaumont also announced production of English-lingo comedy “Late Bloomers,” directed by Julie Gavras, daughter of Costa Gavras. Isabella Rossellini and John Hurt star. “We were attracted to ‘Long Lost’ by Harlan Coben’s talent. It’s a very exciting read,” said Gaumont chair Sidonie Dumas. Massy Tadjedin, writer-director of the Keira Knightley-Eva Mendes starrer “Last Night,” will supervise the writing of the pic’s screenplay. “Late Bloomers” rolls March 2. Set in London, the low-budget comedy turns on a couple who face difficulties growing older together. Gaumont will produce with Sylvie Pialat at France’s Les Films du Worso. Projects continue Gaumont’s drive into English-lingo production, a major growth strategy at the French studio under Dumas and CEO Christophe Riandee.
