“Look at you. You have a baby ... in a bar!” That line, from Reese Witherspoon’s 2002 comedy Sweet Home Alabama, still make me laugh. And now the Oscar winner might have to pretend to be kind to another baby for the benefit of a big-screen comedy.

According to a release, Witherspoon is coming aboard the feature Rule #1 with the intention of shaping it into a starring vehicle. Even better, she has signed Oscar-nominated director Courtney Hunt (Frozen River) to helm the comedy. Witherspoon has said she’ll produce Rule #1 through her Type A banner, collaborating with Brad Epstein of Panther Films and the business venture of Emmett/Furla Films.

If Witherspoon headlines the pic, she’ll play 34-year-old Diana McBride, a woman coping with her OCD who agrees to take in an unpredictable young stranger – who happens to have a newborn baby – in an effort to face her anxieties. Ultimately, McBride’s plan is to win back her estranged husband by convincing him she can handle her chaotic existence.

It sounds like a role tailor-made for Witherspoon’s Type-A tastes. I’m sure she could do Rule #1 in her sleep, so if she does move ahead with it, I’d be interested to see who they cast opposite her as the single mom, and who might play her estranged husband. In the meantime, audiences will be able to catch Reese as one lag of a Tom Hardy-Chris Pine love triangle in McG’s This Means War, and she recently began shooting the high-concept comedy Wish List for Disney.
