Richard Belzer, comedian-actor best known as Law & Order detective John Munch, dead at 78

Richard Belzer, the longtime standup comedian who became one of TV's most indelible detectives as John Munch in Homicide: Life on the Street and Law & Order: SVU, has died. He was 78.

Belzer died Sunday at his home in Beaulieu-sur-Mer, in southern France, his longtime friend Bill Scheft said. Scheft, a writer who had been working on a documentary about Belzer, said there was no known cause of death but that Belzer had been dealing with circulatory and respiratory issues. The actor Henry Winkler, Belzer's cousin, tweeted, "Rest in peace Richard."

For more than two decades and across 10 series — even including appearances on 30 Rock and Arrested Development — Belzer played the wise-cracking, acerbic homicide detective prone to conspiracy theories. Belzer first played Munch on a 1993 episode of Homicide and last played him in 2016 on Law & Order: SVU.

Belzer never auditioned for the role. After hearing him on The Howard Stern Show, executive producer Barry Levinson brought the comedian in to read for the part.

"I would never be a detective. But if I were, that's how I'd be," Belzer once said. "They write to all my paranoia and anti-establishment dissidence and conspiracy theories. So it's been a lot of fun for me. A dream, really."

From that unlikely beginning, Belzer's Munch would become one of television's longest-running characters and a sunglasses-wearing presence on the small screen for more than two decades. In 2008, Belzer published the novel I Am Not a Cop! with Michael Ian Black. He also helped write several books on conspiracy theories, about things like president John F. Kennedy's assassination and Malaysia Airlines Flight 370.

"He made me laugh a billion times," friend and fellow standup comic Richard Lewis said Sunday on Twitter.

Born in Bridgeport, Conn., Belzer was drawn to comedy, he said, during an abusive childhood in which his mother would beat him and his older brother, Leonard. He would do impressions of his childhood idol, Jerry Lewis. "My kitchen was the toughest room I ever worked," Belzer told People magazine in 1993.

After being expelled from Dean Junior College in Massachusetts, Belzer embarked on a life of standup in New York in 1972. At Catch a Rising Star, Belzer became a regular performer and an emcee. He made his big-screen debut in Ken Shapiro's 1974 movie The Groove Tube, a TV satire co-starring Chevy Chase, a film that grew out of the comedy group Channel One that Belzer was a part of.

Before Saturday Night Live changed the comedy scene in New York, Belzer performed with John Belushi, Gilda Radner, Bill Murray and others on the National Lampoon Radio Hour. In 1975, he became the warmup comic for the newly launched SNL. While many cast members quickly became famous, Belzer's roles were mostly smaller cameos. He later said SNL creator Lorne Michaels reneged on a promise to work him into the show.

But Belzer became one of the era's top standup comics. He was known especially for his biting, cynical attitude and his witty, sometimes combative banter with the audience. As one of the most influential comedians of the 1970s, Belzer was a master of crowd work.

"My style evolved from dealing with drunken people at 12, one, two in the morning and trying to be like an alchemist and get the lead of their lives and turn it into golden jokes," Belzer told Terry Gross on Fresh Air.

Belzer would later write an irreverent self-help book titled How to Be a Stand-Up Comic with advice on things like how to apologize to Frank Sinatra when you made fun of him onstage or how to deal with hecklers. One of his favourite lines was: "I have a microphone. You have a beer. God has a plan and you're not in on it."

Belzer often played a standup comic in film, including in 1980's Fame and 1983's Scarface. He had small roles here and there, including in Night Shift in 1982, and Fletch Lives in 1989. But Munch would change Belzer's career.
