For the first 90 minutes of the movie, Affleck and Beckinsale find a nice, appealing chemistry that plays on his strengths as a movie star and hers as a serious actress--he gives her glamour, she gives him smarts. Their truncated romance--the beginning of which is told in flashback so we can get right to the point where he has to leave her to go to England--works, thanks to their charm. They're no Kate and Leo from Titanic (a strategy the film strives hard toward), but they're pretty darn adorable in their own right. Hartnett, as the not entirely unwelcome third wheel, squints bravely but makes only a slight dent in the film. Everyone else in Pearl Harbor--from Cuba Gooding Jr.'s brave navy seaman to Jon Voight's able impersonation of FDR--is pretty much a glorified walk-on, taking a backseat to the pyrotechnics and action sequences that keep the three-hour film in fairly constant motion. But when that action does take hold, Pearl Harbor is quite a thrilling ride. --Mark Englehart
