This technically isn't off-topic, so I thought I'd share some of my casting experiences today.
Actors are a strange bunch. Video games are the "entertainment industry", but they don't really intersect with Hollywood much, except with regard to voice acting. It's a completely separate process.
You can get a casting director (and you'd need to, if you wanted good voice acting and didn't live in LA), but they're pretty expensive. Because There Came an Echo is SAG-AFTRA, I was able to go ahead and rent out some space and bring in actors over a two day span. I didn't know who to go out to, really, so I spammed some well-known agencies (Abrams Artists, Vox, SBV) and got some good responses. It turns out most actors are willing to work for scale +10% ($880/day)...the only ones I couldn't really grab for that were, like, Troy Baker, Jennifer Hale, Tara Strong, and a few others.
Having actors read anything you wrote is a scary experience, and it's often not at all like you imagined it. But shoehorning in exactly what you had in mind means sometimes missing an amazing performance, so I really had my mind changed today on a couple characters. I was able to simply listen...I brought in one friend to record the performances on a mic, and another to read the scenes with the actors.
Everyone is generally polite, but there are a few diva-types. I couldn't dismiss them out of hand, but I would try to wrap the session up as quickly as possible. Others I just didn't want to leave the room because they were so nice. And as much as that shouldn't matter, it does. I'm gonna have to work with these people, and if we don't get along, it's a non-starter for me. So be nice, actors! :O
In the end, I got some pretty amazing names to read for me...Laura Bailey, Yuri Lowenthal, Tara Platt, a few others. They aren't just big names...they're talented as hell. Gonna have to make some tough decisions as I listen to them all back and eliminate files one-by-one, but I'm really excited. = D
