Sandra Bullock is attached to star in and exec produce a Warner Bros. drama that has been set up with Offspring Entertainment’s Adam Shankman and Jennifer Gibgot.

Anne Fletcher, whose Bullock starrer “The Proposal” grossed $317 million worldwide last year, is onboard to direct.

Warner Bros. bought the untitled pitch from writers Pamela Falk and Michael Ellis, who will script. Maggie Biggar at Bullock’s Fortis banner and Offspring’s Matt Smith are exec producing.

Details of the story were sparse, though it’s said to combine elements of “An Unmarried Woman” and “Saturday Night Fever.”

Bullock’s been pursued for high-profile roles following her Oscar win for “The Blind Side.”

She’s considering taking lead roles in two other Warner Bros. projects — Alfonso Cuaron’s space adventure “Gravity,” with David Heyman producing along with Legendary Pictures; and post-9/11 drama “Extremely Loud and Incredibly Close,” with Scott Rudin producing.

Sarah Schechter is overseeing the project for the studio.

“Hairspray” helmer Shankman is prepping to direct the screen version of the Broadway musical “Rock of Ages” for New Line Cinema. Gibgot’s a producer along with Carl Levin, Matt Weaver, Scott Prisand and Tobey Maguire.

Fletcher’s credits include “27 Dresses” and “Step Up,” which Shankman produced. Fletcher is also attached to direct comedy “Matadors,” based on the true story of the Chicago Bulls’ 14-member troupe of male cheerleaders, with Shankman producing.

Falk and Ellis penned “The Wedding Planner.”
