I'm sure many of you might belong to online casting sites like Voices.com. Voice 123, VOPlanet or even be on someone's talent roster at an agency or website. As a casting director specializing in computer games, I can say that by the time we get a request for voices, it's always the last hair of the tail that wags the dog. If I email talents and say, "Please call me no later than tomorrow evening," or give a couple of days notice, I expect at least an email reply fairly quickly. This is not asking for someone to record an audition, because I prescreen on the phone and together, we come up with which parts you're best suited for.
If I don't hear back after I leave you a voicemail message, I hope to hear back within 24 hours. If not, I'm in a bind, since I'm not just one of many casting directors filling the character slots, it's all my gig and I have to cast everything ASAP.
With the online sites, the general rule of thumb is to submit as quickly as you can. The early bird stands a lot better chance than being the 75th person someone hears. I'm guilty of not being able to answer every audition notice from the online membership sites, but if I get asked by one of my agents or in this case, if you were asked by me, that's a different story and you should ALWAYS respond immediately, even if you are saying PASS.
Most agents or websites either don't have time to investigate more details regarding character descriptions or that's not part of what your subscription entitles you to.
With the online sites, you have to give it your best guess, submit with whatever accompanying letter you want to further your cause, along with your direct contact info and hope you get that call. Some people theorize that unless you jump right on an online casting notice as soon as it's posted, your chances dwindle.
Voicebank dot net allows a client to choose whatever agencies they want the casting notice to go to. It can be just one or two, or every agency----and if you get the same audition from multiple agents, it's best to honor whoever sent it to you first.
In the case of agency auditions sent to me to record, I've seen most give anywhere from 2 days or more (depending on when a holiday or weekend falls) to respond.
I have gotten two auditions in the last two days from someone who leads a group on this site, asking for the audition to be done asap the same day. This is unusual, and sometimes it's impossible to do unless you at least have overnight to get the job done.
I'm not blaming anyone, just telling you that as an actor, we can get called by an agent who wants us to show up at a cattle call several miles away the next day and we get the call at 7pm the night before.
You are expected to sacrifice your time and sanity for the biz so welcome to the wacky world of entertainment everybody!
I think stress sometimes brings out the best voices in us. It's our therapy.
Keep the tongue wagging and best to all.
