If Law and Order is canceled, everyone will be out of work
Remember that Saturday Night Live sketch earlier this season, the one where they depicted a master acting class that prepared actors for bit roles on Law and Order? I thought of that after reading this.
The article points out that Law and Order has been quite a goldmine for actors who live and work in New York City. Most prime time shows are filmed in California, so to have a long-running show cast and filmed on the East Coast was an incredible thing for struggling actors trying to get a break into television and more established actors who prefer to live in NYC than LA. But now if it's canceled, that outlet might dry up (even if Law and Order: SVU is safe). As one actor points out, you can do several Broadway shows but if people can see you on just one TV show it's even bigger.
I guess actors can try out for soap operas and 30 Rock, but it's not the same.
