Studios and Hollywood unions have selected March 6 to discuss ways of putting the brakes on runaway production, including perhaps agreeing to contract concessions.

The confab has been set up as a result of the DGA’s recent ratification of its three-year contract with the Alliance of Motion Picture & Television Producers. The guild announced in late November its plan to bring together the AMPTP and the unions to address “possible contract remedies,” or concessions.

In a recent interview, DGA prexy Jack Shea cautioned that details of the get-together had yet to be hammered out, but indicated that there would have to be a quid-pro-quo to help keep work in the United States. “We’re willing to make concessions, but only if it brings work here,” he added.

Invites to the event, to be held at AMPTP headquarters in Encino, have gone out to leaders of DGA, SAG, AFTRA, WGA, IATSE and the Teamsters. The unions have come out strongly in favor of pending federal and state wage-based tax credit legislation, which is largely aimed at keeping low-budget projects in the U.S.

Though no official word has come on possible concessions, speculation so far has focused on TV movies, new series and second-run residuals.

Solutions to the runaway problem, which has been characterized as taking $10 billion annually out of the U.S. to cheaper foreign locations, have caused a rift among unions since last summer. SAG’s national board voted in July to back a controversial initiative to seek a federal investigation into the legality of Canadian subsidies and impose penalties on producers who accept the incentives as a condition of distributing in the U.S.

Backers of the petition yanked the filing last month but plan to refile it within six weeks. DGA, IATSE and AFTRA leaders have opposed the petition on grounds that such penalties are counterproductive in that they could hurt efforts to pass wage-based tax credits and could lead to a trade war.

The petition has also split SAG, with president Melissa Gilbert opposing it and challenger Valerie Harper in support. Additionally, SAG chief Bob Pisano recently ousted legislative affairs chief Lance Simmens, who had carried out the board’s policy on the issue.

The Film & TV Action Committee, the below-the-line org that is chief architect of the petition, was not invited to the confab but said it seeks an invitation. FTAC chief Brent Swift said he opposes concessions since the unions have already agreed to low-budget contracts in recent years.

“We don’t think the problem is greedy grips,” he added.

FTAC also announced Thursday that it will institute a series of lawsuits against the Canadian government under provisions of the North American Free Trade Agreement.

FTAC said the suits will be filed on behalf of small businesses serving the film industry that have incurred severe losses caused by the Canadian film subsidies.
