We only have infrequent open casting/crew call opportunities for film and video projects, but we get a lot of inquiries about how to find out when they opportunities arise. We do often post them on our blog (and on Facebook), but people often miss those posts. In order to ensure that everyone interested has a chance to see all of the calls we send out (likely only a few times a year), we have created a Google group mailing list for making those announcements:
https://groups.google.com/forum/#!forum/launchovercalls
Join up and we’ll let you know when open-call opportunities arise.
