Ann Peacock has been hired to write the screenplay for American Girl for Walden Media, Goldsmith-Thomas Productions and Julia Roberts' Red Om Films.

The movie is based on the American Girl line of historically accurate dolls and books for girls made by Mattel. According to The Hollywood Reporter, while the doll line runs the gamut from pre-Revolutionary War to World War II, the film will focus on Kit Kittredge, who grows up in the early years of the Great Depression.

 No production schedule has been set for American Girl.
