The OP is so right. Gene Hackman is just awesome. Every movie of his I've ever seen has been great. He seems like the nicest guy too. Like if you bumped into him somewhere he would talk with you for like 10 minutes.
He is great as Royal, Popeye, Lex Luther, Normal Dale, etc. etc.
He can be the good guy, the bad guy, the flawed guy, straight man, funny guy.
He's great at any kind of acting. I can't think of a movie he was in that I did not like.
Even "Welcome to Mooseport" was good mostly because Hackman was in it.
I thought the Quick and the Dead was a pretty good movie again mostly because Hackman was in it. I don't like Sharon Stone at all and for him to overcome a not great story line and Stone is pretty impressive. It's like every movie he's in he brings up to a new level.
