No such effort or sacrifice by the pampered stars of today. James Webb, a former advisor to President Reagan and now author and screenwriter, related something he was told by TWO separate Hollywood bigwigs, a director and an actor; "If my child told me they wanted to join the military, I'd do everything in my power to stop that from happening." So much for having actual honor, courage, and commitment. No wonder they can't stay married.
I believe this is why they hate making patriotic war movies. It's deeper than political correctness or '60s "peace-love-dope" liberalism. It's because when you play a true hero, an Alvin York or Audie Murphy or even a Mike Spann, you have to face the fact that you're not fit to shine their shoes. An actor/director/screenwriter can have "it all"; money, looks, power, health...but when they have to really get to know a war hero, as when they must play, or write the character of one, they realize just how phony and insignifigant they really are. Thus, to make themselves feel better, they have to portray America's defenders in a less-than-heroic light.
Fortunately, Hollywood still has some patriotic standard-bearers in high places: Mel Gibson has made several pro-American movies recently, and Arnold Schwarzenegger is a dependable patriot. John Milius is an unabashedly pro-U.S.A. director and screenwriter(Red Dawn, Flight of the Intruder). Many others are out there, secure in the knowledge that they'll never see the accolades their self-hating brethren will.
Guess who gets MY money for their product.
As I recall, Stewart was a bonafide war hero, and even attained very high rank (General?).
He also had a son who served, and was killed, in Vietnam. The only angry or negative thing I ever heard him say publicly was in an interview where he essentially said of the Vietnam war protesters "Damn them all to hell."
