Spader...
Always stood out in this, every time I've seen this. Such a much better actor than the rest.. (though McCarthy and Ringwald aren't exactly Tracy and Hepburn) Just too cool for the room, but, still...you like his prick character for some reason.
Even the small side story about how he professes to have liked Ringwald's character for years (and you're just not really sure if he's playing with her, or going about it all wrong with her..) is great writing.
When, on the bed during his party, he says to his girlfriend "You are worthless, aren't you?" when she gets Andy's name wrong, then..
Just caught this..same deal- at the prom- (almost under his breath) "I don't give a shiht what you do" . You know it's an ad-lib.
Just great!
