"a tale of master liars who just might love each other"

The only thing you can trust about "Duplicity" is its title. Nothing else in this sleek, dizzying entertainment is even remotely what it seems to be. A throwback to the days of old-school caper movies like "To Catch a Thief," "Duplicity" is just the kind of sophisticated amusement you would expect from filmmaker Tony Gilroy. Sure, Julia Roberts and Clive Owen are stars here, but so is Tony Gilroy's crafty tale of master liars who just might love each other.
