The LA Times has an article about a possible Screen Actors Guild strike....
"Now the Screen Actors Guild is pondering its own walkout, possibly as early as next month. But the deepening recession has dampened the militant pro-labor sentiments many celebrities freely espoused last year. With the entertainment business and its tens of thousands of workers still reeling from the three-month writers strike -- and with the larger U.S. economy shedding more than half a million jobs last month alone -- many top performers show little enthusiasm for another smackdown with the studios."
If their is a strike it could affect the filming of NM.
