In Postal, the Postal Dude (Zack Ward) is a dark, brooding character. He has no back story to speak of, “going postal” and deciding to kill everyone in the fictional Paradise, Arizona for an unknown reason.
Sometimes enough is enough and for William “D-Fens” Foster that point was reached in Falling Down. Dressed in his business casual work attire the disgruntled former engineer went on a rampage stealing weapons and confronting anyone that looked at him funny. That’s not really what you would expect from a man with a pocket full of ballpoint pens and a briefcase.
