Kevin Jarre's death was attributed to Natural Causes. A contributing factor was the alcohol's cumulative effects upon his system, which allowed it to give out so early in life. Death by Hollywood.
Sad that such a talented man had such an terrible problem.
He actually had a cameo in GLORY, and had two lines one of which I won't repeat here but the second line was "Give'em hell 54th!", yelled as the regiment was approaching Fort Wagner in formation.
The first line he said earlier on when looking at Morgan Freeman's character had to do with his rank stripes...if you remember you'll know what I mean. It's a funny line but a nasty one.
