Casting Couch: Shelton to Guard Sewell in "Eleventh Hour"

CBS has locked its female lead for drama pilot Eleventh Hour, starring Rufus Sewell as a special science adviser to the government who, along with his female bodyguard, protects the world from abuses of science (read: cloning, super-viruses, etc.)

So who did they get to play Rachel, the fierce female bodyguard who stoically protects Hood from the forces of evil and, well, himself? Why, Marley Shelton (Grindhouse).

While the one time Never Been Kissed star may seem like an odd choice to play a gruff and sensible bodyguard, remember that the role was played in the original British limited series by Ashley Jensen (Ugly Betty), who might also seem like a bit of a stretch in the role. (And yet it worked quite well, in fact.)

The project, produced by Warner Bros Television and Granada, is under consideration for a series order at CBS.

Also at CBS, the network has announced that Britney Spears will guest star on an upcoming episode of comedy How I Met Your Mother. Ouch.

What I'll Be Watching

8 pm: Beauty and the Geek.

Is it really the start of the fifth season? (My god, how time flies.) On tonight's season opener ("Beauties vs. Geeks"), the game gets another unlikely twist: this time around, the beauties will compete as a team against the geeks. Sigh. Really?

9 pm: Last Restaurant Standing on BBC America.

On the sixth episode of this addictive British import, Jeremy and Jane, Grant and Laura, and Tom and Nicola face the challenge of their lives: they must host gourmet evenings with local produce and offer entertainment celebrating local history. Some end up encountering difficulties sourcing seasonal ingredients (really?) and others decide to break the rules...
