Armed with the same airheaded humor he brought to Romy and Michele's High School Reunion, director David Mirkin relies on the clichéd notion that sex turns all men into morons--a conceit that would have worked if the dialogue and sitcom antics were more convincing. As Page's would-be paramour, Jason Lee is rendered intellectually inert, and it's hit-or-miss from that point forward. When the humor hits--as it does with Nora Dunn's rendition of a horrible housemaid--Heartbreakers hints at its full potential. Additional plot twists--not to mention Hewitt's microskirts and Wonderbras--may hold your attention, but you may find yourself harkening back to Steve Martin, Michael Caine, and those happier high jinks on the French Riviera. Singer-songwriter Shawn Colvin has a cameo role as the wedding priest. --Jeff Shannon
