Major Hollywood studios are saying they won't accept pay hikes sought by the Screen Actors Guild in contract talks, suggesting a deal was unlikely before the talks temporarily ended yesterday.

In a statement posted on its Web site, the Alliance of Motion Picture and Television Producers on Wednesday said significant gaps remain between the two sides after 13 days of talks.

The alliance blamed the problems on the guild's insistence on doubling payments that actors receive from DVD sales and demands for "huge increases in compensation and benefits."

The guild responded late in the day with a message to its members saying a deal did not depend entirely on acceptance of those demands. It also stood by its earlier claims that actors were suffering.

"We are not surprised that the employers dispute the economic hardships actors are facing. You know better," the guild said.

The statements were the most public sign thus far of discord in the talks aimed at reaching an agreement before the current contract covering theatrical movies and prime-time TV shows expires June 30.

The negotiations "are going nowhere," said Norman Samnick, an entertainment lawyer who has represented Warner Bros. in previous contract talks with actors and remained close to negotiations. "This thing's not going to be settled until the end of June."

Both sides have said they want to avoid a replay of the 100-day writers strike that shut down TV production and caused an estimated $2.5 billion in economic losses in the Los Angeles area.

The situation already has caused a delay in the filming of some new movies, as producers worry that a possible strike could disrupt shooting, according to a person familiar with the issue who was not authorized to speak publicly and sought anonymity.

A smaller actors union, the American Federation of Television and Radio Artists, is set to begin talks with the alliance Monday, with some observers expecting AFTRA to put up less of a fight, because it already has reached a deal on shows such as "American Idol" and "Survivor."

AFTRA's remaining contract covers only a few prime-time TV shows such as "Curb Your Enthusiasm" and "Til Death."

The producers alliance said it would "continue to work as hard as we can" to reach a deal with SAG over talks that were set to end yesterday, but neither side ruled out another round at the bargaining table following the alliance's negotiations with AFTRA.
