Every fall, when the networks launch their new shows, we start looking for the standout stars.

 They're not always on the best programs. Sometimes, like with this year's just-canceled "Lone Star" from this network, they're on TV for only a couple of weeks before the networks cut their show from the lineup

There is a tipping point where a person stops being an actor and starts being a movie star. It's not just when someone appears in a leading role or a hit movie. It's the moment when an actor goes from being a face to being a bankable name.
For the ten young women on this list, that moment is now. Each has appeared or will be featured in a major 2010 release that not only made an impact with audiences, but also charted a course for their career. You may have see them before somewhere, but soon you'll see them all everywhere.

ROONEY MARA
Age: 25
In her first few acting jobs, she went by her given name "Patricia." But she says she never really liked it, so she started going by her more memorable middle name. This year, she nabbed her first leading role in April's remake of the horror classic "A Nightmare on Elm Street." She'll soon be appearing in director David Fincher's "The Social Network," but she really made headlines when it was announced she'll be re-teaming with Fincher for the upcoming American adaptation of the runaway bestselling book "The Girl With the Dragon Tattoo."

It’s a pretty standard ploy from television execs: once a show is even vaguely popular, take some of the characters, and give them their own series. Hopefully, the money train keeps arriving at the station, and you can keep up your habits of snorting ground mummies off transvestite midget’s asses, or whatever it is that television execs actually do. Unfortunately, for every good spin off (Frasier) there are dozens of horrible ones, ranging from the boring to the downright unwatchable. Here are some of the worst.
