Frozen River screenwriter Courtney Hunt has signed on to direct the comedy Rule #1, starring Reese Witherspoon.

Rule #1 tells the story of a 34-year-old woman trying to cope with OCD, who takes in a young woman with ADD and her newborn baby in an effort to face her anxieties and ultimately get her estranged husband back. The resulting effort takes the woman's already chaotic world spinning into the next level.

Terrel Seltzer (One Fine Day) wrote the script for Rule #1, which was initially set up at Fox Searchlight in 2009 before being put into turnaround.

No production date has been set.
