Hilary Swank will produce and potentially star in an adaptation of Emily Giffin's 2005 debut novel "Something Borrowed" says Variety.

The project, which is out to writers, centers on a Manhattan attorney who becomes involved with her best friend's fiance following her 30th birthday.

Swank and producing partner Molly Smith will develop through their 2S Films. The deal includes rights to Giffin's sequel "Something Blue."
