Negotiations between the Directors Guild of America and the Alliance of Motion Picture and Television Producers continued on Tuesday for the fourth consecutive day and were scheduled to resume today (Wednesday), with some trade and Internet reports suggesting that a tentative agreement could be announced before the end of the week. If so, analysts will immediately examine the kind of agreement the DGA has made with the AMPTP on residuals for digital distribution, the key issue involved in the writers' strike. Many in the industry are hoping that the deal with the directors can provide a template for similar deals with other labor groups.
