Samuel L. Jackson will star with Hailee Steinfeld in RKO Pictures’ Barely Lethal, the Brett Ratner-produced pic that’s being directed by Kyle Newman. From a script by John D’Arco, the action-comedy sees a 16-year old international assassin fake her own death in pursuit of a “normal” adolescence. Jackson will play the girl’s former employer who seeks her out in the small rural town where she’s trying to deal with high-school. Highland Film Group is handling international sales in Cannes with principal photography starting in the fall. RKO Pictures, Hopscotch Pictures and Rat Entertainment produce. Jackson and Steinfeld are repped by ICM Partners.
