There's lots of good movies where you feel that the dialogue could be improvised, but very little was. The "Big Lebowski" was like that where people say "oh, you know, that sounds so..." and we'd always go back and get every man, every ellipses in there the way these guys write it. Because not only is it saying what Michael wants the character to say but the way they all speak kind of creates this tone because it's not exactly real.
Jeff BridgesThere are some actors that want you to call them by their character's name and they have no relationship with you outside of the character. But I like to get to know who I'm working with so that we can relax together, and it's more fun.
