Vince Vaughn and Owen Wilson spark off one another magnificently in this hit comedy about a couple of sneaky divorce lawyers who gatecrash weddings to score the bridesmaids. But their scheme goes off the rails when they run into the daughters (sweet Rachel McAdams and sex-mad Isla Fisher) of US treasury secretary Christopher Walken. The sheer energy of the two leads is addictive but hold the confetti; the comedy is a lot less fluffy than your average romcom.
"Invites are for losers" is the mantra for seasoned spring wedding crashers John Beckwith (Wilson) and Jeremy Grey (Vaughn).
Their modus operandi is simple. Spring confidently up the steps of a church/synagogue or whatever... and cynically cultivate the guests as vague "friends of the family".
After acting as children's entertainers for the little 'uns and dutifully waltzing with the pensioners, the dastardly duo then move in on the gals.
As easy pickings overwhelmed by the caring couple's dewy-eyed decency, it's not long before the ladies swap wedding reception for a bit of rumpy-pumpy.
However, even the rotten scoundrels' deceptive abilities are stretched when they attend nuptials hosted by US Treasury Secretary Christopher Walken - the "Kentucky Derby of weddings."
John finds his customary "love 'em and leave 'em" policy evaporating when he espies Walken's bridesmaid daughter Claire (Rachel McAdams).
Meanwhile, Jeremy's over his head when he woos Claire's nymphomaniac sister Gloria (Isla Fisher) and she declares her undying love (and lust) for him.
Things are racked up another notch when the resourceful romeos are invited by Walken to spend the weekend at the family's weekend home.
Wilson and Vaughn, a comedy duo where neither is prepared to be the straight man, serve Steve Faber and Bob Faber's sparkling script with gusto.
Highlights include a hilarious dinner table scene where Gloria erm, relieves, an increasingly manic Jeremy under the tablecloth and her gay brother's subsequent attempt to play "tummy sticks" with a persecuted Vaughn.
It's a mite long for a comedy but is such good fun you could forgive the fizzing chemistry of Vaughn and Wilson staying that long on screen.
Wilson, in particular, appears to be having a good time - he gets to fondle Jane "Dr Quinn Medicine Woman" Seymour's re-constituted breasts.
