So I've managed to get past the SAG Catch-22, (I booked a principal role in a SAG commercial), but I need some advice on the Theatrical Agent Catch-22, (you can't get a good theatrical agent without Guest-Star level roles, but you can't get Guest-Star level roles without a theatrical agent). Any thoughts and/or links to previous forum discussions on this topic would be appreciated.

You can get a theatrical agent by getting co stars from CD workshops or wowing thing at an Agent showcase.

Or maybe get strong clips or produce your own

Everybody in this business has had to traverse these "Catch-22's" and there isn't a set formula to do it. There are as many stories as there are actors. I follow the mantra of "learn, shoot stuff, meet people .. repeat as necessary".

I like Chester's mantra.

I maintain that the best way to find an agent is to start by asking your circle of actor friends and colleagues. ONLY ask people who've seen your work and seem to like it. Personal recommendations are the best entree into an agency, I believe. No friends with agents? Time to get into a great theatre company, class, group or just find a new hangout that's frequented by actors.

Also, do what I did. Aim lower. I launched my career by finding a good B-level agency willing to submit for co-star roles (many won't).
