The Hollywood Reporter says that Martin and film actress Uma Thurman are the latest additions to the starry company, which also features Academy Award winner Whoopi Goldberg, Equus' Richard Griffiths, Madison Pettis and former "Sopranos" stars Tony Sirico and Steve Schirripa.

The winter TV offering will boast songs by Paul Williams, who penned the score to "The Muppet Movie." TV watchers can also expect, of course, appearances by Kermit, Fozzie, Gonzo and Miss Piggy, among other Muppet friends.

"Letters to Santa," according to the industry paper, "is set on Christmas Eve when Kermit and company mistakenly avert three letters en route to Santa Claus, which triggers a race against time to bring a happy Christmas to the kids whose wishes were lost in the mail."

Last season ABC presented "Elmo's Christmas Countdown."

Jesse L. Martin's theatre credits also include the Broadway productions of Timon of Athens and The Government Inspector. He was a "Law & Order" regular for several seasons.
