Director Denise Di Novi keeps the pot boiling along the way to a climactic catfight in which hair is pulled, fingernails are deployed and a fireplace poker is brandished. But Di Novi and screenwriter Christina Hodson throw in some unsavory and gratuitous ingredients that limit the appeal of "Unforgettable" even for those with a taste for cinematic junk food.

These include Tessa's emotionless -- and futureless -- parking-lot tryst with a good-looking stranger she just met and David and Julia's escapade in a restaurant bathroom. In another scene, Julia no sooner turns on the taps of her bathtub at home than the experienced moviegoer knows that her silky robe is coming off on screen.

It's not silk that sells, after all.

The film contains occasional violence with some gore, cohabitation, strong sexual content including graphic scenes of casual and premarital sexual activity and masturbation, brief rear and partial nudity, about a half-dozen uses of rough language, a few crude terms and a mild oath. The Catholic News Service classification is L -- limited adult audience, films whose problematic content many adults would find troubling. The Motion Picture Association of America rating is R -- restricted. Under 17 requires accompanying parent or adult guardian.

CAPSULE REVIEW

"Unforgettable" (Warner Bros.)

Feverish domestic drama in which an obsessive ex-wife (Katherine Heigl) conspires against her former husband's (Geoff Stults) fiancee (Rosario Dawson), eventually framing her rival for murder. Director Denise Di Novi keeps the pot boiling but, together with screenwriter Christina Hodson, throws in some unsavory and gratuitous ingredients that limit the appeal of her film even for those with a taste for cinematic junk food. Occasional violence with some gore, cohabitation, strong sexual content including graphic scenes of casual and premarital sexual activity and masturbation, brief rear and partial nudity, about a half-dozen uses of rough language, a few crude terms, a mild oath.
