Keira Knightley is in negotiations to step into the lead in Lynn Shelton’s indie dark comedy, Deadline said.

Laggies, written by Andrea Siegel, follows a woman who hides out for a week with a 16-year-old (Chloë Grace Moretz) under the pretense of going to a work retreat after her boyfriend proposes. Sam Rockwell is also lined up to co-star.

Anne Hathaway was in negotiations to star just last month but scheduling conflicts with Christopher Nolan’s Interstellar forced her to drop out. Steve Golin, Alix Madigan and Rosalie Swedlin will produce Laggies for Anonymous Content.
