Have you noticed lately that the new faces cropping up on TV series in starring roles are often actors you've never seen before -- or if you have, it was in a supporting role of a feature or a foreign TV show? Think about it, Lee Pace as the Pie Man on Pushing Daisies, Jonny Lee Miller on Eli Stone, Nikolaj Coster-Waldau in New Amsterdam, Michelle Ryan in Bionic Woman, all of these leads are relatively new faces. That's one way to cast series. Another is for big stars to take to TV, if not for the first time, than for a return.

In an interesting article at IGN.com, blogger Travis Fickett points out that there used to be a line of demarcation between the worlds of acting: film actors vs. television actors. But nowadays the stars are going back and forth a lot more fluidly.

This is no laughing matter. John Gilmore, executive director of Autism United, said today that CBS must apologize for an insensitive remark made on the Julie Chen-hosted reality show Big Brother during last week's episode. One of the contestants, a man named Adam, said that if he was the show's big winner, he would use the money to start a hair salon for people with developmental disabilities. Adam went on to say he wanted a beauty shop "so retards can get it together and get their hair done." When Sheila, another contestant, protested, "Don't call them that," Adam declared that, "Disabled kids. I can call them whatever I want. I work with them all day, okay?"

According to CBS's Big Brother web site, Adam is a public relations manager for an unnamed foundation. The 29-year-old is from Cherry Hill, New Jersey, but is now living in Delray Beach, Florida.
