Just when Erica Kane thought she was out of options, the world's richest man may come to her rescue.

Warren Buffett will make a cameo appearance on the ABC daytime soap "All My Children" in May, in an episode when he visits Erica, a character convicted of insider trading. Buffett, 77, plays himself in the episode, show publicity director Michael Cohen said in an interview Wednesday.

Buffett will appear with actress Susan Lucci, who plays Erica, and Jill Larson, who stars as Erica's friend Opal Cortlandt. In one scene, Buffett excuses himself to take a phone call from Microsoft Corp. Chairman Bill Gates.

Buffett, the chairman of Berkshire Hathaway Inc., met show creator Agnes Nixon at the 1988 Winter Olympics, according to Nixon. The two struck up a conversation about writing. A month later, after reading Buffett's comments in the Berkshire Hathaway annual report, Nixon bought some stock so she could continue enjoying his writing.

"The broker said that's the most expensive magazine subscription he'd heard of," said Nixon, who says she's in her late 70s. "I didn't think he was a writer. I thought he was a financial genius."

Buffett wasn't available to comment, said spokeswoman Jackie Wilson. "All My Children," an hourlong show based in the fictional suburb Pine Valley, celebrated its 38th anniversary in January, Cohen said.

Buffett also was on the show in 1992. One-day pay for a daytime actor is $759, according to the American Federation of Television and Radio Artists.

"He's so down-to-earth and always willing to go along with a good gag," said Frank Betz, a partner at Carret Zane Capital Management. "He's always playing his ukulele and singing at charity events in Omaha. Some of those performances make your hair hurt they're so bad."

Berkshire, based in Omaha, Neb., fell $410 to $128,490 Wednesday in New York Stock Exchange composite trading. The shares have gained 19 percent in the past year.

Nixon, who says she's attended several of Buffett's annual shareholder meetings, plans to screen Buffett's "All My Children" cameo at the next gathering on May 3, before the episode airs, she said.

"He's made people millionaires," Nixon said. "He doesn't have time to have a recurring role. I think he would certainly do it again sometime."
