What's your favorite Kevin Costner and Will Smith movie?

Will Smith is a hard one because I like Independence Day, I think best, But I also like I Robot and Legend. Kevin Costner, Field of Dreams. (But then I also like Robin Hood). I don't go crazy as to accents, so Kevin Costner's speech mode doesn't bother me. If it did I would have to say "The Big Chill" is my favorite Kevin Costner movie.
