The Wrap's Hunter Walker has details on HBO's latest pilot, Tilda, the Diane Keaton-led comedy which may or may not be based on the life of notorious Hollywood blogger Nikki Finke. Walker cites one unnamed source, an executive, who describes the plot of the Bill Condon-scripted project as "a broken woman, alone in her apartment," while another maintains that the titular character doesn't have much of a resemblance to Finke. "A lawyer for the network said HBO's official stance on the show is that the Tilda character is a compilation of many Hollywood media personalities, rather than a straight-up caricature of Finke," writes Walker. "Right. And that guy Ari Gold on Entourage is a "compilation" of Hollywood agents." [Editor: I still need to read the pilot script, which is sitting on my hard drive here.] (The Wrap's The Box)

The seventh season premiere of Bravo's Top Chef was 27 percent off from its 2009 season opener, luring 1.8 million viewers overall. [Editor: I would agree with The Hollywood Reporter's James Hibberd: the brand has definitely been diluted by the addition of spinoffs to the mix... and I don't think Bravo did the series any favors by rushing the flagship back on the air the week after Top Chef Masters wrapped.] (Hollywood Reporter's The Live Feed)
