Palahniuk's novels tend to be darkly humorous

Palahniuk's novels tend to be darkly humorous creations that defy definition—and are generally regarded as near impossible to adapt. The only one previously transferred was Fight Club, directed by David Fincher and released in 1999. Describing the plot of Choke proves arduous, even for Gregg. "It's what I would call a black romantic comedy," Gregg says. "It's not an easy one to break down." The plot centers around a sex addict named Victor Mancini (Rockwell) who purposely chokes at restaurants in order to be rescued by Good Samaritans he can then emotionally blackmail for money. The goodwill cash keeps his ailing mother (Huston) in a mental institution, where Victor becomes involved with a doctor (Kelly Macdonald) who believes Victor is a clone of Jesus Christ. And never mind his day job as a performer at a colonial village, where he earns the ire of the Lord High Charlie (Gregg, in a hilarious supporting turn).

Fortunately, Gregg never had to try to pitch the Byzantine plot. "It was brought to me as a novel to adapt, so I skipped many steps," he says. "I went crazy for it and pulled in every favor and begged and pleaded and threatened in order to make it myself. By the time I had to explain it, it was already a script that was making people uncomfortable."

Though he had appeared in a few high school productions, Gregg says he never thought he would become an actor. "I wanted to be in punk bands or be in trouble," he recalls. He played soccer at Ohio Wesleyan University until he dislocated his thumb, and on a whim he tried out for the school production of Much Ado About Nothing. He landed the lead but didn't consider pursuing acting as a career, though he admits, "It got under my skin a little." He dropped out of school and moved to New York, and then his friend Mary McCann turned him on to a class being taught at New York University by David Mamet and William H. Macy. "It was there, working with those guys, where I first discovered acting could be something interesting and noble—a profession you could give something of yourself to, not just have it be about ego gratification," says Gregg.

Gregg graduated from NYU's Tisch School of the Arts and, along with Mamet and Macy, was a founding member of Atlantic Theater Company, where he continues to serve on the board of directors. He remained busy on stage, appearing in A Few Good Men on Broadway and directing an acclaimed revival of Mamet's Edmond, while also making trips to Los Angeles for film and TV work.

When a friend suggested he try directing for film, Gregg was intrigued. "I said, 'I'd love to, but how do you do that?' " he recalls. "They said, 'The best thing you can do is write a script.' So I started to write for that purpose: to create something I could glue myself to so adhesively that someone would put up with letting me direct it." He admits he had always been interested in writing but had been too intimidated. "The writers I knew and worked with in New York—David Mamet and Craig Lucas and people like that—I was so blown away by what they accomplished as playwrights and screenwriters that I found the whole concept terrifying." But at this point, he was living full time in L.A. and found that the alienation of a new life helped urge him on: "If I hadn't had that quiet boredom, I don't think I would have sat down and started writing."

One of the first pieces he wrote was a cabaret evening called The Big Empty "that was all about how bitter I was in L.A.," he says with a laugh. "We did it at a bar, and it cost $10 to see, but people laughed a little, and it made me go back and write something else. I just kept chopping away. I knew I couldn't just sit there." His acting agent soon began representing him as a writer and sent out a supernatural-themed script Gregg had completed. "DreamWorks didn't want to make my movie, but they had a ghost-story idea, and they were interested in having me try to write that," he says, still sounding surprised. "So I got hired to write a movie." Gregg calls his experience on What Lies Beneath "a two-and-a-half-year film school" and praises director Robert Zemeckis for "keeping me around and involved."

He also noticed that when one career began to flourish, the other followed suit: "The funny thing is, as soon as I started working as a writer, suddenly I started to get a lot more paying work. Before, I'd been doing a lot of theatre or guest-star roles, and you can't stay alive too long doing that." He had notable turns in Mamet's State and Main and Nicole Holofcener's Lovely & Amazing, and was nominated for an Independent Spirit Award in 2000 for his work in The Adventures of Sebastian Cole, while continuing to field writing assignments. "Then I was sent Choke," he recalls. "And I remembered why I started writing to begin with: so that I could make a movie. And I said, 'Maybe this is the one.' "

Gregg was instantly drawn to the offbeat story and thought the fact that Palahniuk wrote in such a filmic way would make adapting it easier. He was wrong. "The only conversation I had with Chuck, he said, 'I'm just going to give you one hint: Don't be too faithful to the book.' I thought, 'That was nice, but he had to say that,' " Gregg recalls. "I told myself, 'There is so much funny, visually fascinating stuff in here; I'm just going to kind of do a cut-and-paste and turn it into a screenplay.' Then I spent a year and a half struggling." It was only after he decided to lose the first-person narrator and throw the book in the drawer that the screenplay began to take shape. "Some of the things that were most interesting in the book didn't land quite the same way as a movie script. I think that's pretty common," he says. "You have to turn it into its new self."

Once he had a script in place, Gregg knew he had to find the perfect leading man to win the audience over. "This script was something that made people uncomfortable, and Victor does a lot of sketchy, sleazy things," he notes. "It was clear I needed someone who wasn't a lothario type and you could really care about." He had met Rockwell when they performed together in 1991 in the play Unidentified Human Remains and the True Nature of Love. "It was this deranged-serial-killer play where everybody was naked most of the time," Gregg says with a laugh. "It was kind of experimental, and everyone would have to stand frozen upstage while everyone else did their scenes. I realized after about a week or two that I was racing through my murders just to get back to my freeze position so that I could watch Sam." Rockwell clicked with the Choke script immediately. Says the actor, "Clark did a great job capturing that very specific and unusual Chuck Palahniuk tone, which is kind of like Ken Kesey meets John Irving."

With Rockwell on board, Gregg found that other actors became interested. "I don't know if Anjelica would have taken the script seriously without Sam," he confesses. "A lot of actors are big Sam Rockwell fans, and she was one of them. I think she agreed to meet with me based on that, and we hit it off."

Gregg also worked closely with casting director Mary Vernieu, who he says worked for free for a number of years. "Mary Vernieu is one of the very best in the business," he says. "She's done all kinds of movies, and she's always bringing in somebody you don't know who just knocks your socks off." For the role of Denny, Victor's best friend and co-worker, Vernieu suggested Brad William Henke and urged Gregg to watch his work in the films SherryBaby and Me and You and Everyone We Know. "I knew I wanted Victor's best friend to be very large and for them not to seem like two buddies but a main guy and his gentle-giant sidekick," Gregg notes. "It's a hard type to find, but Mary said, 'I know who this is.' He was exactly what I was looking for: that sweet-hearted guy who can crush you like a coconut."

For the role of Victor's love interest, Gregg had thought of Macdonald early on, having been a fan of her work in Trainspotting and Gosford Park, but this was before the actor showed she could easily play American in No Country for Old Men. "When we started to cast in earnest, everyone said, 'She's British; we don't have the money to fly anyone over to audition or meet with you.' So I kind of put her out of my mind," he notes. "Later I was talking to Sam, and he suggested her. I told him we couldn't get her over here, and he said, 'No, she's here. She just finished this Coen brothers movie.' And three days later I was meeting with her in Los Angeles."

Having done more than his fair share of auditions as an actor, Gregg found it fascinating to be on the other side of the casting process. "As an actor, I don't love auditioning. It's a scary thing; it's a hell of a thing to kind of hang it all out there in a room with a video camera and a tired director sometimes. And yet I've done a lot of it, and some percentage of the time I'm able to get good wood on the ball," he notes, adding, "I certainly had a lot of empathy and feeling for the actors who came in and read for me. People were like, 'You don't have to work with them all that much.' And I thought, You do. You really do."

Gregg shot Choke in 25 days in July 2007 while on hiatus from The New Adventures of Old Christine. Having worked with a variety of directors, from Bryan Singer to Robert Benton, Gregg knew what he looked for in a filmmaker. "The old saw everybody says is to have somebody who knows what they want. And that's a big part, for them to have a clear idea of the story they're trying to tell," he says. "But the ones who are clear enough about what they want to achieve that they are very open about how they get there—those to me are the people I don't want to leave at the end of the day."

He also had mixed feelings about directing himself while playing colonial re-enactor the Lord High Charlie. "In one way, it's nice. The odds are very slim the director is going to say anything too mean to me," he says with a laugh. "But about seven days in, I was just beginning to get the crew to pay attention to me, and suddenly I'm ordering everybody around in a frilly shirt and knickers. Any semblance of authority I had evaporated quickly."

The film premiered at the Sundance Film Festival in January, earning a Special Jury Prize for best work by an ensemble cast. The win capped a long journey for the hyphenate who never intended to even become an actor. "I do sometimes have people come up to me and ask about how to plan a career like mine, and I want to laugh," he admits. "Because for years I felt like I was always on the brink of being finished. But one of the things I learned from being in a theatre company was to always be working. Don't get rusty; always be doing something." He also remembers knowing he would be in for a struggle from the beginning. "You hear these depressing lectures when you start out: 'Of the 50 of you in this room, 48 will be dead by morning!' And maybe some people aren't meant to be doing it, but if you really love it and keep plugging away, I feel like everyone gets a shot."

And though Gregg admits he isn't sure how the rest of the world will react to "the demented comedy about the sex addict" when the film goes into limited release Sept. 26, he has plenty of other projects to distract him. He recently began work on the fourth season of Old Christine and is starting to write an ensemble piece to direct. "That is, if they'll let me after this one comes out," he notes. "This next one may be as twisted as Choke. And I don't have Chuck Palahniuk to blame this on."
