If you want to broaden the appeal of a romantic comedy, it helps to grab an array of actresses -- like say, a girl who is not only known as a modern Nancy Drew, but also a hot-tempered Hero, a woman who starred in one of the hot rom-coms of 2008 (Sex and the City), and a girl who can smack down baddies in an alternate time of superheroes and impending doom.

The Hollywood Reporter posts that Kristen Bell, Kristin Davis, and Malin Akerman have signed on for a new film called Couples Retreat. Now Akerman, at least, has had some iffy luck with this genre, so here's what ups the ante -- it's written by Iron Man Jon Favreau, and will be directed by collaborator Peter Billingsley (better known as the Christmas Story kid). So, it's not your everyday comedy. In fact, "rom" has been completely left off the genre placement of this project so far, but it is a comedy about romance. (Is there a difference?!)

The story involves four couples working on their relationships at a tropical island resort, so who are the men in romantic peril? Jason Bateman gets to be married to Bell, Favreau is also co-starring as Davis' husband, and Vince Vaughn gets to canoodle Malin. As for the fourth, Faizon Love is attached, but there's no word on his leading lady.
