Movies about con men usually have too little conning, and movies about people who twitch usually have too much twitching. I love to watch the con man's side of a telephone conversation or be a fly on the wall of a high-pressure sales office, but a few obsessive-compulsive tics go a long way. Ridley Scott finds a nice balance with Nicolas Cage as Roy, a neurotic "con artiste" in Matchstick Men. Cage is funny when he tries to convince people to give him his meds, but I'm always glad when he gets those meds and calms down. Sam Rockwell plays his hipper, messier partner Frank as if he's Chuck Barris, if Chuck Barris were a different sort of con man. They work in the late-morning glare of southern California where they lie to people who they think deserve it, carry bundles of cash in briefcases, and always choose the right eyeglasses for the job. Thrown into the middle of this odd mixture is a third element, a dollop of cuteness: a 14-year-old daughter that Cage didn't know he had. After Thirteen and Lost in Translation, Matchstick Men is the least serious in a string of recent movies about how adults relate to young women, even though the movie makes sure Cage learns a couple of lessons about life and pharmaceuticals before it's over. More enjoyable than those lessons is the way the disparate elements combine into some lightweight high jinks and the way a few moments of real suspense remind us that Ridley Scott knows what he's doing.
