We enjoyed watching the sparks fly as Julia Roberts and Clive Owen matched wits in Tony Gilroy's smart spy-vs-spy thriller romance Duplicity. Their volatile chemistry called to mind classics of the genre like Cary Grant and Audrey Hepburn in Charade. The background for the high-stakes corporate espionage was hilariously brought to life by the antics of battling mega-CEOs Tom Wilkinson and Paul Giamatti, with the tone set in an opening sequence of the competitors physically wrestling one another in front of their appalled executive teams and their corporate jets. Gilroy's peel-back-the-onion style of revealing the story works fairly well to keep you wondering what's really going on, and who's really doing what to whom, although I had figured the final wrinkle before the end. Even so, it's a funny and suspenseful way to spend a Saturday night.
