What are the best quality classes in Chicago?
I am interested to enroll in some acting classes, here in Chicago. I served for about ten years and really need to test my skills. I know many people – Acton, the Victory Gardens, Steppenwolf, Acting Studio Chicago Actors Studio – What are opinions on the type of class? And someone should start with experience?
You need to network! You already know where to go, so the best thing you can do is ask to see if you can attend a course and see how the teacher teaches, watch certain shows / plays that some of these students act so you can evaluate what kind of talent that these studios have. Universities, please contact / colleges / theaters and talking to acting teachers / teachers / managers there and see who they recommend as an interim coach. Everybody knows / know each other to find information should be easy.
