She's not just fast. She's very fast.

Meet Daphne, the speedy new character on NBC's "Heroes," who plans to give the show's superhumans -- especially time traveler Hiro and his sidekick, Ando -- a run for their money when she debuts on the popular NBC series' upcoming third season, which went back into production last week.

"I'm stealing a secret that's been kept in Hiro's family for a long time that he's just now found," actress Brea Grant said during a break in filming on location in a high-rise building in downtown Los Angeles. "He stops time right as I grab it, but in that second it took him to grab it, I almost make it out of the office."

Grant doesn't know much about her mysterious new character. Daphne's superpower allows her to operate at three speeds and leave a supersonic wake in her path when Hiro stops time. Grant's not sure where Daphne is from, but she does know the Speedster -- that's what she calls herself -- has been on her own for a long time.

"Her character is supposed to be Hiro's Joker," said Masi Oka, who plays Hiro. "Batman has The Joker. Hiro has Daphne. This is the season where Hiro finally finds his arch nemesis, and it happens to be this Speedster. I kind of equate it more to Wile E. Coyote and the Road Runner, except Daphne says more than 'meep-meep.' " (Derrik J. Lang, Associated Press)

Dan Rather has filed an amended lawsuit against CBS that says other TV networks refused to hire him because of the damage executives at his former company did to his reputation after a disputed 2004 report on President Bush.

Rather's lawyer, Martin R. Gold, said new papers were filed because a judge said in April the initial lawsuit did not specify how CBS injured Rather in his occupation. The judge said the veteran newsman could submit an amended complaint.

Gold said the new papers, filed Wednesday in Manhattan's state Supreme Court, detail the injuries that Rather claims.

Rather says he met with CNN, ABC, and NBC in 2006 to talk about employment after his departure from CBS, but they refused to hire him because he brought "too much baggage."

The news anchor said that when he met CNN officials in 1997, they offered him $6 million a year to work for them. He said issues with his CBS contract, plus CBS's proposed match of CNN's offer, caused him to stay where he was. In a spring 2006 meeting, court papers say, Rather met again with CNN executives and with ABC and NBC representatives. None would consider him, saying in various ways that the Bush story had generated too much controversy.

Rather and his agents also met later with Fox, A&E, History Channel, HBO, Discovery Channel and National Geographic television networks, court papers say, but all passed, saying he was "too hot to handle" or "words to that effect."

Rather's papers say he could have defended the Bush story, but, relying on CBS's promises to defend him and extend his contract, he was "misled into remaining silent and unfairly taking the brunt of the blame for misconceptions about the broadcast."

He left CBS on June 16, 2006, after more than 40 years at the network. He has since signed with HDNet, a cable network with limited distribution.

"Although now working, Mr. Rather's [on air] exposure is dramatically limited and, accordingly, his reputation and standing in his trade and profession have not recovered from the damage caused by the defendants' conduct," court papers say.

CBS replied by saying: "Mr. Rather is trying to put forth fraud complaints that the court has already determined to be legally unfounded. We believe he will fail a second time. We will file an appropriate motion to dismiss."

Rather sued CBS Corp. last September, claiming he was booted out of his evening news anchor post and given lesser assignments after controversy over a September 2004 "60 Minutes II" report about Bush's military service.

The report, aired two months before the 2004 election, said Bush avoided Vietnam military service by using his father's connections to get into the Texas National Guard. Once in the National Guard, the report said, Bush shirked and failed to complete his duties.

A panel formed to investigate the piece said the network "failed miserably" to authenticate the memos on which the story was based. (Samuel Maull, Associated Press)
