No more Saturday Night Live after this week
Most shows have Nov/Jan episodes in the can and then no more after that.
So LOST and 24 could be hit hard depending on how far they got along. Heroes Origins has already been canceled.
99% of what you see on TV in Feb and on will be reruns/reality tv.
And this strike will probably be long unless the AMPTP does an about face. If it gets to Feb then forget about it...at that point the WGA will just hold down till June so they can strike together with SAG.
