Five more actors are joining the cast [1] of He's Just Not That Into You. [1]
Specifically, Jennifer Connelly, Kevin Connolly, Ginnifer Goodwin, Bradley Cooper, and Justin "I'm a Mac" [2] Long are signing up for the film, which is based on the guide to dating [3] by "Sex and the City" staffers Greg Behrendt and Liz Tuccillo. Barrymore's Flower Films is producing, and Ken Kwapis of "The Office" [3] and License to Wed [3] is directing.

Sit tight for this plot summary.
According to the Hollywood Reporter:

Jennifer Connelly plays a woman stuck in a tired marriage with Cooper's character. Kevin Connolly, meanwhile, is a man pining after a woman, still not cast, who is having an affair with Cooper. Goodwin is a young woman obsessed with Kevin Connolly's character who tries to set up accidental meetings with him only to run across his friend, played by Long, who takes her on as a "My Fair Lady" experiment.

And Drew?
She "plays a woman perpetually confused by dating" — as I would be, too, if I were friends with that mess of people.
