The One About When Groucho Marx and Dick Cavett Became Great Friends

Cavett knows he had the goods back then. “When I see myself on Decades, I’m often surprised at how good I am,” he said, referring to a network that carries reruns of his show. “That’s a terrible thing to say in public, but I’m completely entertained by myself.”

Marx was entertained, too. He saw in Cavett a kindred spirit, a fellow wit.

“Groucho was young in mind, although old in body at that point,” Bader said. He was still widely beloved, known for the television show “You Bet Your Life,” which he hosted from 1947 to 1961. The counterculture had embraced the anarchic spirit of movies like “The Cocoanuts” (1929), “Duck Soup” (1933) and “A Night at the Opera” (1935). He was a sort of éminence grise in American comedy, still revered by younger comics like Cavett. And Marx in turn never tired of the stage lights.

“Dick gave Groucho this wide open forum, which he didn’t necessarily have when he went on other shows,” Bader said. “He would just take over.”

Cavett tears up in the film as he recalls Marx’s death in 1977 at age 86. “We had lost Captain Spaulding,” he says in the film, referring to the name of the character Marx played in the 1930 movie “Animal Crackers.” For nine years, their friendship was a joyous on-air affair.

But he still has the memories and stories, which he loves to share. Like the time a couple recognized the two men on a New York sidewalk and the man asked Marx to say something insulting about his wife.

Marx paused, Cavett told me, then replied: “‘Well, with a wife like that, you should be able to think of your own insults.’

“Let’s put it his way,” Cavett added. “I’ve never enjoyed a guest more.”
