Those of you who are fans of the book series on which this fall's "Gossip Girl" is based already have a good sense of who's who on the show, which premieres Sept. 19. But to help out the rest of us, the CW has put together a series of short videos introducing us to the show's six main Upper East Side teens. Below the jump, check out the introductions for Serena, Blair, Dan and the rest. If you've read the books, I'm curious: How well do these descriptions match what you were expecting?

I love me some Simon Pegg, as I think pretty much everything he does is hilarious. And I know many of you — like me — adore Hank Azaria. So the U.K. preview for this fall's comedy Run, Fat Boy, Run should please a good number of Pegg and Azaria fans.

Curiously, the movie was written by Michael Ian Black and directed by David Schwimmer. Pegg plays Dennis, an out-of-shape dude who leaves his pregnant fiancee Libby (Thandie Newton) at the altar. Five years later, he believes that she's the love of his life and decides to win her away from her new man (Azaria, who looks unbelievably good in this trailer) by running his first marathon. Let the training montages begin!

In true "Desperate Housewives" fashion, the newest family to move to Wisteria Lane is dripping with mystery. Actors Nathan Fillion, Dana Delaney and Lyndsy Fonseca recently chatted with TV Guide about their family, one of two new households on the lane this year. Here's what we learned about their characters:

• Katherine Mayfair, Delaney's character, used to live on Wisteria Lane with her daughter, Dylan (Fonseca), and an aunt, but she moved away 12 years ago under — you guessed it — mysterious circumstances. When she returns, she's with her new husband, Adam (Fillion), a gynecologist with an "unsavory" secret in his professional life.
• A perfectionist and control freak, Katherine is a rival to Bree; apparently there will literally be a throwdown over lemon meringue pie.
• Dylan was once friends with Julie Mayer, but she remembers nothing from that time, and the memory loss leads people to suspect something dark in her past; as a teenager, she's kept on a strict schedule, "almost like a dog."

"Desperate Housewives" is also the latest show to get the music video treatment from ABC, with glam scenes of the original five housewives set to the new Jennifer Lopez song "Mile in These Shoes." To watch the video, as well as a behind-the-scenes segment with some of Delaney's first scenes, read more
