(Rated PG-13, 110 mins.) With all the Hollywood hype on couples splitting, timing couldn’t be better for this story of Kiki Harrison (Julia Roberts), a devoted personal assistant to beautiful, narcissistic megastar Gwen Harrison (Catherine Zeta-Jones). She also happens to be Gwen’s sister. Life as siblings was tough before but this time it’s at an all-time peak when Roberts agrees to help Gwen and her estranged actor husband Eddie Thomas (John Cusack) reunite for one last public appearance to promote their latest movie. Veteran press agent (Billy Crystal), on the brink of being replaced by his younger protégé, is put in charge of masterminding this highly anticipated event that of course backfires in more ways than one. A “Final Analysis” feel with that award winning Robert’s “Notting Hill” smile make for a feel-good summer movie especially since Roberts took a back seat in this anti-glamour-less of a role. Because of Zeta-Jones playing a diva, her hard edge doesn’t make for good chemistry with Cusack, (the movie’s only flaw), although she deals a good hand at comedy. Hank Azaria plays a lover, Stanley Tucci an eccentric studio guy and Christopher Walken as a controlling director, all well-suited and perfectly cast.
