Variety reports that the Universal and Working Title picture is tapping Richard Curtis. He’s the writer behind Love, Actually and War Horse. Director Sofia Coppola was attached to the project at one point, but that fell through.

From Variety:

Moretz had been the frontrunner for the role even while Coppola was still attached; some insiders point to Coppola’s unwillingness to go with a star like Moretz as her impetus for parting ways with the project. Following Coppola’s exit, the studio still wanted Moretz for the role but did not want to make it official until a writer was attached for a final draft.
