by starring in amy heckerling's " clueless " two summers ago , alicia silverstone proved she wasn't just another pretty , pouty ingenue , showing a buoyant comedic craftiness that blew all previous jobs -- namely a stint as the aerosmith girl and a silly turn as the lethal lolita of " the crush " -- out of the water . 
her only work since that 1995 gem has been in june's " batman & robin , " where she overcame the underwritten role of batgirl . 
now , she's the star and producer of " excess baggage , " a hopelessly phony film that demonstrates how an ill-composed story can drag an otherwise solid performer down to its level . 
silverstone's emily t . hope is stuck with a billionaire father ( jack thompson ) who neglects her emotionally . 
in an outlandish plan to gain his affection , she fakes her own kidnapping -- emily uses an electronically disguised voice to call her dad and set a pricey ransom , ties her legs together and mouth shut with duct tape and locks herself in the trunk of her bmw . 
but before the police can " rescue " her , professional auto thief vincent roche ( benicio del toro ) jimmies the locks , hot-wires the engine and makes off with both the car and emily , who's still trapped in the back . 
when vincent discovers emily , the two don't exactly hit it off -- she annoys him , he annoys her , and at the advice of his slimy car salesman partner ( harry connick , jr . ) , he decides to drive her out to the middle of nowhere and leave her there . 
along the way , of course , they get into a whole heap of trouble , and come to realize that being together is the only way to get out of their sticky , felony-studded situation . 
it doesn't help matters that emily and vincent are being trailed by cops , crooks and even her shady uncle ray ( christopher walken ) , who's wise to his niece's ploys for attention and has mafia connections . 
for at least a half-hour , " excess baggage " bounces along fast and efficiently . 
during this time , emily and vincent sport engaging personalities as well as a nice role-reversal twist -- she's an awfully aggressive , combative victim and he's quite the aloof , seemingly vulnerable captor . 
but once it's past its set-up , the situation suddenly becomes uninvolving as the story tries to be too many things at once . 
a road movie , a teen comedy , a mob thriller , a drama about family relationships -- you name the cliche and " excess baggage " likely covers its territory . 
of course a romance develops between the two leads , but it all seems forced , and thus characterization is manipulated to cause the finally happy outcome . 
 " do you like my tummy ? " 
emily coos to vincent at one point in the film . 
huh ? 
did i miss something ? 
the hard-edged , foul-mouthed grrrl is suddenly gone and replaced with a pair of batting goo-goo eyes . 
then again , " excess baggage " becomes so weak in so many areas that the personality transplant is not a complete surprise . 
a supporting cast attempts to do what they can with colorful but empty secondary roles , but the movie isn't game enough to use them all and therefore seems overcrowded . 
motivations keep shifting , resulting in an often confusing narrative . 
scant existing story background confuses matters even worse and adds to the growing list of unanswered questions . 
 " excess baggage " has too many characters , too much plot and juggles with one arm behind its back and a remaining shaky hand . 
i loved silverstone's turn in " clueless " as an aloof , pampered beverly hills matchmaker inspired by jane austen's " emma . " 
looking back at the skill she displayed for comedy there , it's simple to justify any high expectation or enthusiasm that i had mustered for " excess baggage . " 
sadly , however , " excess baggage " is no " clueless . " 
but , on the other hand , it is clueless .
