The French master teacher Philippe Gaulier has worked with stars like Sacha Baron Cohen. But at 78, are his methods, which include insults, outdated?ÉTAMPES, France — It’s unlikely anyone alive has made more clowns cry than Philippe Gaulier.In a supposedly more sensitive era, hundreds of people regularly travel from all around the world to a small town an hour outside of Paris to study clowning with Gaulier, a gruff 78-year-old éminence grise known for his blunt, flamboyantly negative feedback. Wearing a pink tie, beret and stern look over a bushy white beard on a recent tour of the school, he looked the part of the guru — a mischievous one. He pointed at a large photo of himself teaching in China and joked he was “Clown Chairman Mao.”In his office, sitting across from his wife, Michiko Miyazaki Gaulier, a former student who is now a colleague, he made no apologies for his pugnacious style, saying students who are not funny have a choice: “You have to change or leave the school. You are boring. If you want to stay boring all your life, you will never be a clown.”Gaulier has been teaching clowns for about half a century, but his stature has grown in recent years, becoming an influential and divisive figure of considerable mystique, the Dumbledore of round red noses. The primary reason for his raised profile is the success of Sacha Baron Cohen, a former student who praised Gaulier on Marc Maron’s podcast in 2016 and described receiving bad reviews from him in a 2021 appearance on “Late Night With Seth Meyers.”“I was always interested in comedy, but it was Gaulier who helped me understand how to be funny,” Baron Cohen wrote in the preface to Gaulier’s book “The Tormentor.”Clowns remain a staple of the circus, but the reach of the ancient art is much wider these days, with a growing theatrical scene as well as performers crossing over into other forms. The alumni network at Gaulier’s school, where many make lifelong connections, is expansive — spanning film and theater (Emma Thompson, Kathryn Hunter), circus and live comedy, with students like the Los Angeles comedian Dr. Brown becoming gurus themselves. Another protégé, Zach Zucker, is the host of Stamptown, a popular showcase of cutting-edge comics in Brooklyn, its name inspired by the town of Gaulier’s school. “He has become the name to drop,” Geoff Sobelle, an acclaimed performer and former student, said about Gaulier’s reputation among clowns.In a two-hour interview last month, Gaulier, speaking in English, came off less like a teacher than a very funny insult comic, teasing and trash-talking, tossing jabs at everyone from Slava Polunin, the Tony-nominated Russian clown (“For children who has problem to sleep, can be good”) to the legendary mime Marcel Marceau (“He’s a maniac with his gestures”). Asked if someone can be funny who didn’t make him laugh, he said it was possible, before turning back to me, gesturing at my clothes: “It’s possible that you with your glasses, your hair, that you are funny,” he said, before the punchline. “And someone really well-dressed is, too. The opposite of you.”He’s allergic to anything that smacks of pretension, which inevitably inspires one of his favorite expressions: “of my balls,” as in Slava is a “poetic clown of my balls.”Compared with other clowning teachers, Gaulier said he does not emphasize technique or physical virtuosity. His pedagogy aims for something more intangible, nurturing a childlike spirit, a sense of play onstage. The most important quality in a clown is keeping things light and present, and, as he said with the utmost respect, stupid. Finding “your idiot,” as he calls it, is the essence of clowning, which, unlike comic acting, requires a performer to stick with the same character. “A clown is a special kind of idiot, absolutely different and innocent,” he said. “A marvelous idiot.”Gaulier “helped me understand how to be funny,” Sacha Baron Cohen has written.Cedrine Scheidig for The New York TimesGaulier said he could put a red nose on anyone and tell how they played as a 7-year-old. Students, who do in fact do exercises in red noses, describe this in gushing terms.“He liberated me,” said René Bazinet, a highly respected German-Canadian clown who has worked for years with Cirque du Soleil. “In my first year, I had to read a poem, and he kept stopping me, saying, ‘Why are you clearing your throat? Say the poem. Why are you doing this? Why that?’ And one moment, my brain just opened up. His way of attacking the falseness was a relief to me. I was becoming an idiot.”This process can sometimes sound like a masochistic cleansing ritual. “He just insults his students all day long until they start laughing and their ego gets out of the way,” Bazinet said. “You are taking your ego to the slaughterhouse.”Former students inevitably have stories of bruising feedback, usually told with the affection of grizzled war veterans. Kendall Cornell, who leads an all-female clown troupe, Clowns Ex Machina, recalled a lot of tears, but also a “mind-blowing” experience that taught her things she didn’t learn in other classes. There’s even a Facebook group that collects insults called “Philippe Gaulier Hit Me With a Stick.”The criticisms include “You sound like overcooked spaghetti in a pressure cooker” and “You are a very good clown for my grandmother.” He frequently focuses on the eyes. “If you are funny,” he told me, “you have funny eyes.”Gaulier is even stingy with compliments for his most successful alumni. Asked about Baron Cohen as a student, he said: “Nice boy. Tall.” Pressed for more, he added, “He’s a guy who when he understands something, he’s going to sell it. That’s enough.”When he was 8, Gaulier, who grew up in Paris near a circus, was kicked out of school for punching his gymnastics teacher. Seven decades later, he has no regrets. “He was a bastard,” he said, explaining that the instructor made students march like in the army. “I hate the military. Teachers, too.”His ambition was to be a tragic actor, but every time he tried to do serious work in drama school, he said with resignation, everyone laughed. This led him to a class with the renowned mime and master teacher Jacques Lecoq, whose pioneering training was rooted in clowning, improvisation and mask work. Gaulier became a performer who, with his partner, Pierre Byland, had a hit clown show, during which he broke 200 plates every night.Five Movies to Watch This WinterCard 1 of 51. “The Power of the Dog”: More
