FILM: Katherine Heigl + Gerard Butler

Gerard Butler's last romantic venture, P.S. I Love You, amassed $52 mil domestically and got creamed by critics, while Katherine Heigl's 27 Dresses is already up to $47 mil after two weeks and didn't take as much of a beating critically. Maybe some of her good luck will rub off on him--and she'll need it to since they'll be each other's romantic love interest in The Ugly Truth. Butler will play the TV host of a chauvinistic segment called ''The Ugly Truth'' and Heigl will play a loveless morning show producer who gets roped into a series of Butler's experiments to prove his theories on relationships. The upside is that he's supposed to help her find love. This has potential for being slapstick funny, which we know Heigl is capable of, but can Butler pull the role off being a cock-sure cad?
