I can say that with 100% certainty that this project will move on ahead. HOWEVER, I can't fill the cast with the current auditions I have. If you've been looking to try out for something there is a big opportunity for you right here. If I can't fill the cast I will have to scout to fill the remaining roles, though I'll either work with people I haven't cast before or, if I have worked with them before, place them in roles they don't typically play.
If I receive more auditions though there'll be a near-certainty that scouted roles will become fewer or farther between. Your best chance of landing a role would be to try out, not hope for a scouting message.
