Reese Witherspoon will reunite with her "Walk the Line" director James Mangold on "Three Little Words" for Lime Orchard Production.
An adaptation of the memoir by Ashley Rhodes-Courter, the story centers on the relationship between a young Florida girl who entered the child welfare system when she was four, and the unpaid volunteer who discovers her nine years later.
The volunteer must search for and convince the biological mother to surrender her parental rights so the teen can begin a new life. Witherspoon will play the volunteer, while Amanda Seyfried is in talks to co-star as the biological mother.
Lewis Colick and Michael Petroni penned the script, while Mangold, Jami Gertz, Cathy Konrad, Daniela Taplin Lundberg, Riva Marker and Daniel Crown will produce.
Filming begins in September in Florida.
