Katherine Heigl on Strike: 'Be Fair and Share!'

The cast of “Grey's Anatomy” put down their stethoscopes and picked up some protest signs to join a group of picketing Hollywood writers yesterday.

Patrick Dempsey, Ellen Pompeo, Sandra Oh and T.R. Knight stepped right of the “Grey's” set in their scrubs and onto the streets during their lunch break.

Knight told the Associated Press that their last day of filming will be this week.

Said Sandra, "This matter is way too important not only for our writers, but ultimately everyone who makes movies, everyone who makes entertainment here in this town and again for the rest of the world."

Patrick added, “It's really a big tragedy to be out here striking at all. I think there are going to be a lot of people affected by this, that have families, that live paycheck to paycheck, that upsets me profoundly. But at the same time, I do feel that the writers deserve a better break on the deals they have been getting."

The strike began Monday after negotiations between the Writers Guild of America and the Alliance of Motion Picture and Television Producers failed to determine how writers should be paid when their shows move to the Internet.

Already, several shows have announced they'll soon be out of production, like “The Office,” “Desperate Housewives” and “Two and a Half Men.”

One of televisions most popular shows, Fox's “24,” will have to shut down production until 2009.

Season seven of the hit series will take Kiefer Sutherland's Jack Bauer to Washington, D.C., and “Extra” was in the nation's capitol with Kiefer as the news of the strike broke.

If the show is able to continue filming, Kiefer says fans can expect more thrills.

“It doesn't get any better,” Kiefer said. “Finally for the people who are in the White House on our show they get to actually step outside, and you believe where they are."

Kiefer also revealed that last season's bad guy Tony Almeida, thought to be dead, is back. Kiefer's character will have to battle it out to save the country, and Kiefer admitted that keeping up with that action-packed schedule is a tall order.

“Well I think one of the great qualities of Jack Bauer is his integrity,” he said. “And obviously in hindsight we all have moments where we look back and go, 'Gosh I wish I had done that differently,' but certainly in those moments he's doing the best he can and I think that's what I've related to him, and audiences have as well."
