I'm an Exec Producer of a low budget movie that will shoot in Atlanta in a few weeks. This low budget model is not my area of expertise, as I'm based in LA, and most of the budgets I've worked in are much higher. I was awestruck when the Atlanta producers told me the casting director received approx 3000 submissions for this low budget movie. The casting director and the Atlanta filmmakers pulled selects for the group to review. When I started reviewing the audition videos, I was so impressed and delighted by the actors who had given us their time. Honestly, I was blown away that there are so many talented actors out there. And I applaud the casting director who selected great new talent to read.
While some of the selected auditions were SAG, others were non-union or SAG Eligible. Casting directors are looking for great talent. They will push that new talent up to the top alongside more established, union talent. The odds might be long, and the dedication required is intimidating, but you will be seen if you keep at it. Break a leg!!
