Mighty Funny

Take away the exploding drummers and foil-wrapped cucumbers, and This Is Spinal Tap is a movie about people who take themselves seriously. Which is why it's a comedy classic. Christopher Guest used that same seriousness in three more improvised comedies: Waiting for Guffman, Best in Show and a new folk-music film, A Mighty Wind. Guest, who writes his movies with Eugene Levy, reunited with Tap alumni Harry Shearer and Michael McKean as the Folksmen in this film. All four sat with TIME's Richard Corliss and Josh Tyrangiel for a folksy conversation.

AFTER SPINAL TAP, WHICH WAS DIRECTED BY ROB REINER, HOW DID CHRIS TAKE OVER AS THE DIRECTOR OF THIS TROUPE?

CG: Have I? When Harry and I went to Saturday Night Live for one year in '84, I said, "I don't care what happens here; I'll direct these little films." I think I just knew that the comedy that can come from improvisation was so much funnier than other stuff I was seeing. I take my son to movies that are supposed to be comedies; you're lucky if there are five laughs in the entire 90 minutes.

HS: Maybe if you got him high he'd like it better.

CG: It occurred to me. I'm trying.

MM: Like he hadn't thought of that.

A MIGHTY WIND IS AN IMPROVISED MOVIE, YET EUGENE AND CHRIS ARE CREDITED AS WRITERS.

CG: We wrote the story. The story is very specific and has a beginning, middle and end. All the scenes are broken down--there are 120 scenes, and everyone knows what happens in every scene. And there's a backstory created for all the characters.

CAN THE ACTORS EMBELLISH THEIR BACKSTORIES?

CG: No. It's very important that everyone has the same information going into a scene, because we can't contradict one another. When jazz guys are improvising, they know what key they're starting in, and the melody they improvise off of is not just arbitrary. That's exactly what this is: you have a skeleton of something you can build on.

EL: The actors work with wardrobe and makeup and hair. They design the look that they're going to have.

CG: I say to the actors, "What do you want on the desk in this scene? What do you want to wear?" In a conventional movie, the costume designer says, "There'll be stuff hanging in your trailer. This is what you're wearing." I say to our wardrobe person, "You go with the actors to find the right sweater." It has to be comfortable...

HS: Mine was itchy.

CG: That was my idea.

MM: You should have said something, maybe when we were shooting.

HS: I've been holding it in for so long.

YOU SHOT 80 HOURS OF FOOTAGE. HOW DO YOU PULL IT ALL TOGETHER?

CG: I don't see anything until I sit down with the editor. I'll look at everything and start talking and taking notes. But unlike a real documentary, where you don't know the story until you shoot, we know what the story is. We have to pick scenes that tell the story. So maybe something is funny, but if it's off story, it's gone.

ARE YOU GUYS INVOLVED IN THE EDITING?

HS: No, but Chris is very generous in the sense that during the editing process, we're talking and he says, "Come by, look at some stuff."

MM: We don't say anything.

HS: [Imitating Guest.] "Don't say anything! But come and look."

MM: "Bring food."
