Here is the trilogy (quadrilogy?) of William Atherton's yuppie douchebaggery:
Ghostbusters (1984), Walter Peck
The EPA official who ended up unleashing all the ghosts onto Manhattan. Stupid government bureaucracy.
Real Genius (1985), Prof. Jerry Hathaway
Tried to use students and their research to gain large government contracts. Got his house filled with popcorn in the end.
Die Hard (1988), Richard Thornburg
Same to somewhat diminishing returns in Die Hard 2: Die Harder (1990)
Except on an airplane.
Bonus: the creators of Lost knew him to be so good at playing a dick that they had him guest spot as the principal to Michael Emerson's Ben in the sideways universe in the last season. He excelled here at what he did best.
Just for fun: the runner-up: Paul Gleason.
Sadly, Paul Gleason passed away in 2006. You should check out his because, of course, he plays well known jerks in these movies below, but he was on a ton of stuff, pretty much every popular television show of the eighties. He was even in the TV movie Ewoks: The Battle For Endor. Pretty amazing.
But we are here to talk about his classic movie jerkdom:
Trading Places (1983), Clarence Beeks
His comeuppance in the end is simply amazing.
The Breakfast Club (1985), Principal Richard Vernon
You mess with the bull, you get the horns.
Die Hard, Deputy Chief Dwayne T. Robinson
"Looks like we're gonna need some more F.B.I. guys."
Eh, we can call it a tie, I guess.
