Lucy: Natasha Richardson, Bonnie Hunt, Justin Theroux, Kip Pardue and Zoe Saldana have signed to star in Maggie Greenwald's drama Lucy for Gotham-based banner Plum Pictures.

Based on the 1990 novel by Jamaica Kincaid, the story follows a 21-year-old girl from the West Indies as she spends the summer in a sheltered New York WASP community. She takes a job as a nanny for a wealthy couple but soon notices the cracks in their seemingly perfect facade.

Saldana (The Terminal) will play the title character, with Richardson as her employer and Hunt as the latter's best friend Dinah. Pardue plays Dinah's younger brother, with whom Lucy falls in love, and Theroux plays a local artist who befriends her.

Key character of Richardson's husband is yet to be cast.
