So here they go:
"(W)e would not enter negotiations with the AMPTP unless we were within shouting distance of an agreement on our two most important issues-- jurisdiction for our members to work in new media and appropriate compensation for the reuse of our work on the Internet and other new media platforms," ... DGA president [Michael Apted] wrote. "We've spent the last few months discussing these and related issues with the studios, and we've been doing intensive research on these points for the past year and a half. Now we believe it is time to move forward with the goal to hammer out an agreement."
Formal negotiations between the Directors Guild of America and the Alliance of Motion Picture and Television Producers start later today. How long do they last? I'd say somewhere around a month. But of course I've got no thorough-going knowledge of the complexity of all the issues through which the two sides must churn, so we could say I've got my head up my large intestine and not be wrong.
But a month seems to be about the norm.
However much time it takes, if and when the two sides reach an agreement, it changes the dynamics of future negotiations for the WGA and SAG. Whether the other guilds like those new dynamics or not.
