The all-star cast of He's Just Not That Into You already includes Jennifer Aniston, Kris Kristofferson, Scarlett Johansson, Jennifer Connelly, Kevin Connolly, Justin Long, Ginnifer Goodwin, Bradley Cooper and Drew Barrymore, who’s one of the producers.

Now it may expand by one Ben Affleck; he’s in negotiations to join the ensemble film, which is scheduled for a 2009 release.

Ken Kwapis (License to Wed, The Sisterhood of the Traveling Pants) will direct.

 The movie’s based on a humorous self-help book of the same name by Greg Behrendt (a standup comedian and consultant for Sex and the City) and Liz Tucillo (Sex and the City’s executive story editor). At first glance, the book doesn’t seem like a good candidate for adaptation. But chapter headings like "He’s just not into you if he’s not asking you out" (or calling you, or dating you, or having sex with you) do seem as if they might weave together into those "interconnected story arcs" promised by the advance publicity.
