Casting Roundup: "Jezebel," "Betty," "FNL"

• The totally awesome Dianne Wiest has joined the cast of "The Return of Jezebel James", playing the mother of Coco (Lauren Ambrose) and Sarah (Parker Posey). That's three awesome ladies on one screen, especially given Wiest's particular skill at playing the crazy mother. Here's hoping the show itself can match up.
• Speaking of awesome, multi-time Emmy winner Marlo Thomas — aka "That Girl" — will guest-star on "Ugly Betty" as a jewelry company owner with a weakness for younger men, including one Daniel Meade. Saucy!
• TV Guide says Alyssa Milano will play a love interest for Earl on the upcoming season of "My Name is Earl." Could it be a serious love match? She's reportedly on board for at least eight episodes.




• Also from TV Guide: Edie Falco has booked a three-episode run on "30 Rock," former ER doctor Michael Michelle has a guest spot on the upcoming season of "House" as a CIA doctor, and Jessalyn Gilsig of "Nip/Tuck" will play Tami Taylor's sassy sister on "Friday Night Lights," sticking around for at least six episodes.
• So you wanna be one of the new "American Gladiators"? Now's your chance. NBC is holding a cross-country search for gladiators and contenders, starting in Los Angeles on Saturday. Hmm, that's not much time to get in shape ...
