Like most romantic comedies, Picture Perfect has a wacky premise: Advertising copywriter Kate can't get a promotion unless her boss thinks she's living beyond her means (he thinks it makes his workers hungry), and she can't get dreamboat Kevin Bacon unless he thinks she's unavailable. So friend Darcy (Illeana Douglas) makes up a fianc for Kate based on a wedding videographer named Nick (Jay Mohr). Naturally, Nick will soon have to play the lover's role and will fall for Kate while doing so.

Fortunately, movies have ways of making the audience forget such preposterous premises. Engaging stars go a long way, and Aniston and Mohr are attractive both separately and together. Aniston has an antic, Mary Tyler Moore-ish quality that plays well on the big screen; she creates a character nicely distinct from her TV persona. My only complaint is that she consistently neglects to button her blouses, as if all we came to see was cleavage. Jennifer, sister, you've got talent--you don't need to work blue.

Jay Mohr, who had a cup of coffee with Saturday Night Live and turned heads as evil agent Bob Sugar in Jerry Maguire, has a deadpan sincerity that clicks with Aniston's flightiness. It really works in the farcical sections of the script, like the hilarious dinner set-piece in which Nick foils Kate's every attempt to play out the script she's written. At such times, the movie's script feels like it's being ad-libbed; in reality, it's just loose enough to direct the stars' energies without stifling them. Director and cowriter Glenn Gordon Caron keeps the timing sharp but doesn't clutter the screen or the plot.
