According to The Hollywood Reporter, Elizabeth Banks and Rachel Weisz are in negotiations for DEFINATELY, MAYBE, a romantic comedy from Working Title and Universal Pictures.

Separately, Banks has snagged a lead role in "Joe Claus," Warner Bros. Pictures' Vince Vaughn comedy.

Written and directed by Adam Brooks, DEFINATELY, MAYBE centers on a soon-to-be-divorced political consultant who has to answer some hard questions from his 11-year-old daughter as he explains his promiscuous past. Ryan Reynolds, Derek Luke and Isla Fisher already have been cast. Banks will play Reynolds' college sweetheart who dumps him for his brother, but the two reunite years later. Weisz will play a woman Reynolds dates after Banks.
