Back Stage's Jessica Jardine has an interview with True Blood's Mariana Klaveno, who plays Bill's maker, the devious vampire Lorena. "That's one of the really brilliant things about the show," said Klaveno. "[The writers] show how vampires relate to humans, and vice versa: What parts of humanity do they maintain, and what parts do they not? And obviously some do so more than others. Bill fights really hard to maintain some of his humanity, and someone like Lorena doesn't. There's parts of her that are just not there anymore, nor does she want them to be, because that's part of her human life, and that's dead and gone now. But it's interesting to me that love seems to be something that stays with them. Love and jealousy and greed and lust—-those all carry into your vampire life." (Back Stage)

Say goodbye to Happy Town... again. ABC has yet again yanked the low-rated mystery series from its schedule after the network began to burn off the remaining episodes on Wednesday evenings this summer.

Meanwhile, ABC will bring back the final two episodes of The Forgotten on Saturday, July 3rd and the last two installments of Eastwick on Saturday, July 10th.

TV Guide Magazine's Will Keck has details on just who Vanessa Williams (Ugly Betty) will be playing when she drops by Wisteria Lane this fall. Keck, citing unnamed sources, reports that Williams, who is set to join the cast of ABC's Desperate Housewives, will play Renee Filmore-Jones, described as "an old college chum of Lynette Scavo" (Felicity Huffman) and bitter rival of Lynette's back in the 1980s. "Renee has been married for years to a handsome, hunky man (likely an athlete) named Keith Jones (I'm so picturing NYPD Blue hunk Henry Simmons in this role, though it's yet to be cast)," writes Keck. "They have no kids, meaning Renee has spent all these years just being a housewife supporting her man. But she's reached a time in her life when she wants to do more. Oh, one last thing: she has a secret." (TV Guide Magazine)
