Grant Jumps 'In Her Shoes' For Fox

Susannah Grant ("Erin Brockovich") is stepping toward "In Her Shoes" for Fox, reports Variety.

Grant has agreed to pen the screenplay, based on Jennifer Weiner's soon-to-be published comic novel.

"Shoes" revolves around a sibling rivalry between an irresponsible party girl and her sister, an ambitious attorney, who move in together.

Weiner created a splash last year with "Good in Bed," her bestselling debut novel about a Philadelphia reporter obsessed with her weight and men.
