As an assist to clients of The Rosenzweig Group, I've been known to read with them for their self tapes, where I've "played" everything from a cop to a pregnant woman. The thing is: There's an art to being a reader. As a guide for young actors, I thought it would be helpful to lay out some tips for those coming up, who might recruit readers for their tapes. Did it with the help of Alexis Koczara, casting director for Emmy-nominated shows such as ABC's Black-ish and Cobra Kai on Netflix.
