Kramer is dead.

That's the word from Michael Richards, the loose-limbed actor who immortalized the character on Seinfeld.

Richards, 53, now says he doesn't want anything to do with his famed alter-ego.

"I don't want to be Kramer anymore!" Richards declared in an interview with The Guardian newspaper of London. "He was nice for 10 years, but now I'm running away from him."

Richards last week made his London stage debut starring in a revival of Arsenic and Old Lace at the Strand Theatre.

The wire-haired actor formerly known as Cosmo is playing the role of Jonathan Brewster, the character played by Raymond Massey in director Frank Capra's famed 1944 movie starring Cary Grant.

Richards, who has rarely spoken publicly since the demise of his short-lived NBC sitcom The Michael Richards Show in 2000, said starring in his own show was a mistake.

"About three shows in, I thought, 'What am I doing?' " he said. " 'I just got off 10 years on a TV show. Why am I going back into this?' I was glad to get out!"

He doesn't miss Seinfeld at all, but values his fame from the show for the acting jobs it gets him today.

"Do I miss Seinfeld? No!" he said. "It had a good run. And the popularity to me is only useful to the extent that it gets me work."
