Answered. Some guy trying to send you "free emails" to help you network as an actor. If you have to specify free something is up.

I got called twice by this number but no message was left. I work as an extra in LA and assumed it might be a call casting me, but if that is the case, they would leave a message.

Also considered it to be a call back from a casting but I don't answer numbers I don't know. They called twice, no message.  Frustrating.

I missed the call.  They did not leave a message.  I thought it might be a casting as well but I think they would have left a message for that.

i did. i thought it was maybe for a casting..
