The two largest actors unions have reached a tentative contract agreement with television and film producers, apparently averting another potentially devastating Hollywood strike, officials said Friday.

The accord was reached Thursday night when the Alliance of Motion Picture and Television Producers accepted in substance proposals by negotiators for the Screen Actors Guild and American Federation of Television and Radio Artists, a statement issued by both unions said.The apparent settlement came during highly unusual talks proposed by the unions and convened March 14, a full two months before formal negotiations were scheduled on contracts that expire June 30.

The Joint National SAG/AFTRA boards of directors will meet Monday in Hollywood and Wednesday in New York to consider whether to recommend the contract to the combined membership of 102,000 television and film performers.

If the boards recommend approval, ratification ballots will be mailed to the rank-and-file within two weeks.

Details of the settlement were not released.

The Screen Actors Guild's chief negotiator, Ken Orsatti, said: "We are very pleased by the results of our initiative. We have responded to industry concerns about the need for new bargaining methods to avoid the devastating strikes this industry has suffered in recent years. We believe we have made a deal that is advantageous to both labor and management and the industry as a whole."
