Finally Some Good News: Uma Thurman Joins Latest Muppets MovieDespite how wicked and cynical and just plain fucked the world grows, people can still appreciate a good thing now and then. As evidence, Uma Thurman and Law & Order star Jesse L. Martin have both just signed on to appear in the upcoming Muppets Christmas special, "Letters to Santa: A Muppets Christmas." In the special, which airs on NBC this December, Uma will play Santa Clause's flight attendant while Martin portrays a mailman who opens the show with a song-and-dance number. As is mandatory, Kermit, Fozzy, Gonzo, Miss Piggy, and the rest of the crew are determined to save Christmas for some tots whose letters to Santa were lost in the mail. "Thurman and Martin join previously cast Whoopi Goldberg, Tony Sirico and Steve Schirripa, Richard Griffiths and Madison Pettis, along with Kermit, Fozzie, Gonzo, Miss Piggy and the rest of the muppets gang. The special, from Muppets Prods., will feature songs by The Muppet Movie songwriter Paul Williams." [TheHollywoodReporter]
