Details of the deal, which covers TV and feature film production, will not be made public until after a SAG board meeting on Sunday. If the board approves the agreement, SAG will present it membership for ratification.

Formal talks between the actor’s union and the movie studios began more than a year ago. The last round of negotiations collapsed in late February after the studios made a final, take-it-or-leave-it proposal.

The previous SAG contract expired in June 2008. Since then, SAG’s member actors and actresses have been working under the terms of the expired agreement pending resolution of negotiations.

The contract is similar to the one studios presented to SAG previously. The agreement is the result of negotiations between David White, SAG’s interim executive director, and top media executives including Walt Disney Co. CEO Bob Iger and Warner Bros. Chairman Barry Meyer.

The turning point in the contract talks came in January, when the union’s former chief negotiator, Chief Executive Doug Allen, was ousted by moderates who took control of SAG’s board in elections last year. At that point it became clear the union wouldn’t call a strike.
