French producer/distributor Gaumont has picked up rights to mystery novelist Harlan Coben's France-set Long Lost, and is planning an English adaptation.

According to Variety, the novel is 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.

Massy Tadjedin 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.

The projects continue Gaumont's drive into English-lingo production, a major growth strategy at the French studio under Dumas and CEO Christophe Riandee.
