Actress Eva Longoria, star of ABC's Desperate

Los Angeles ? Production of the hit show “Desperate Housewives” and at least six sitcoms filmed before live audiences will be halted as a result of the writers strike – developments that raised the stakes Tuesday in the walkout targeting movie studios and TV networks.

Producer Alexandra Cunningham said “Desperate Housewives” will stop production today after running out of scripts on Tuesday. Shows that have already been completed won’t last until Christmas, she said.

Sitcoms that will stop the cameras include “Back to You,” starring Kelsey Grammer and Patricia Heaton, which will not return from a planned hiatus, said Chris Alexander, a spokesman for 20th Century Fox Television.

Star Julia Louis-Dreyfus said production also stopped on her CBS show, “The New Adventures of Old Christine.”

In addition, “‘Til Death,” on Fox, and “Rules of Engagement,” “Two and a Half Men” and “The Big Bang Theory,” all on CBS, also will end filming.

It was not immediately clear how many of the programs might already be finished.

The sitcoms are typically written the same week they are filmed, with jokes being sharpened by writers even on the day of production.

The disclosures came during the second day of the strike by the Writers Guild of America against the Alliance of Motion Picture and Television Producers. Pickets returned to studios in Los Angeles and New York.

In Toluca Lake, near Warner Bros. studio, writers converged on a house serving as a location shoot for “Desperate Housewives.”

“We write the story-a, Eva Longoria,” about 30 strikers chanted, referring to a star of the hit ABC show.

Shooting continued Tuesday inside the house despite the protests, said Chandler Hayes, a spokesman for ABC.

Marc Cherry, executive producer and creator of the show, said the writers had his blessing to picket as long as they were respectful to the actors.

When shooting ended, Longoria left the house and handed out pizza to strikers. “We are done, and we’ll be on the lines supporting you,” she told them.

The strike began Monday after last-minute negotiations failed to produce a deal on how much writers are paid when shows are offered on the Internet. No new negotiations were scheduled.
