Recently, there are many calls for extras or background talents from background actors casting companies such as Central Casting.
Here is how to sign up with Central Casting in New York: http://www.centralcasting.org/NY/actors/index.html.
If you sign up with Central Casting, you will get an account on nycasting.com for free. But you can also sign up for an account at nycasting.com to get more casting calls by paying as little as $25 a year.
I heard that BackStage also have casting calls. But I have never used it. Here is the website: http://casting.backstage.com/.
You can also get free casting calls by subscribing to ActorsFirstNY newsletters at http://groups.yahoo.com/group/ActorsFirstNY/. The acting jobs there are mostly non-paying jobs. You will get free meals with non-paying jobs though.
