Rumor Has It... is awkward and unfunny. While Sarah's grandmother, the chain-smoking, haughty Katherine Richelieu (Shirley MacLaine), offers comic moments, the movie pretty much abandons her once Sarah finds the model for Benjamin Braddock. Never thinking just to ask her father, Earl (Richard Jenkins), about her dead mother's past, Sarah instead imagines her mom was happiest with this other man, as they spent a weekend in Mexico just before her marriage to Earl.
The film perks up briefly when Beau heads to Pasadena, where he encounters Katherine. Unimaginatively accompanied by Ennio Morricone's spaghetti Western theme, she stalks out to confront her erstwhile lover, and then, pfft. The film retreats from this sparky relationship, so full of raw resentment and regrets, to refocus on the terminally dull Sarah.
