Barry B. Longyear
For folks who liked this movie, I would suggest checking out some of Barry Longyear's other works.
Just seeing Enemy Mine is only seeing a tiny fraction of this author's excellent work.
In particular, I particularly liked his short story collection "It Came From Schenectady" ... the intro by Mr. Longyear is hysterical by itself, and there are a load of great stories there.
One of his most powerful novels is "Sea of Glass"... if you read it, you will never forget it. Incredible stuff. I wish I could visit "The Shrine To Why?" from that book.
