This is why Bill Murray is always watchable. (Well, some of why…)

You have a lot of lines in this one that get tons of laughs I doubt were on the page. It’s all in the rhythm, the delivery. How do you pitch something like that? How do you make something out of nothing?

I have developed a kind of different style over the years. I hate trying to re-create a tone or a pitch. Saying, “I want to make it sound like I made it sound the last time”? That’s insane, because the last time doesn’t exist. It’s only this time. And everything is going to be different thistime. There’s only now. And I don’t think a director, as often as not, knows what is going to play funny anyway. As often as not, the right one is the one that they’re surprised by, so I don’t think that they have the right tone in their head. And I think that good actors always—or if you’re being good, anyway—you’re making it better than the script. That’s your fucking job. It’s like, Okay, the script says this? Well, watch this. Let’s just roar a little bit. Let’s see how high we can go.

But you asked how you get the comic pitch. Well, obviously a lot of it is rhythm. And as often as not, it’s the surprising rhythm. In life and in movies, you can usually guess what someone is going to say—you can actually hear it—before they say it. But if you undercut that just a little, it can make you fall off your chair. It’s small and simple like that. You’re always trying to get your distractions out of the way and be as calm as you can be [breathes in and out slowly], and emotion will just drive the machine. It will go through the machine without being interrupted, and it comes out in a rhythm that’s naturally funny. And that funny rhythm is either humorous or touching. It can be either one. But it’s always a surprise. I really don’t know what’s going to come out of my mouth.

The rest of the interview is also well, well worth your time. Get over to GQ, and read it…
