Didn't know he was having heart problems. At some point I saw Armageddon, but I have since tried to block it from my memory, so the ony thing I've seen with him in it is The Green Mile. Which is good enough for him to get a farewell nod for me. There are so many things that had to work in that film for it to work as a whole, and the right John Coffey was a big one of them. And he nailed it. If you watch the bonus features on the DVD, he talks about how excited he was to get the part. You can see the joy in his eyes just thinking about it.
