Should I be concerned about what a casting director will think about me taking online acting classes?

Since Online Acting Classes are relatively new to the business and growing rapidly,  it could still take a little convincing. A good way to convince the casting director that your skills are solid is by applying the techniques you've learned from and doing a great job with your audition. It might also be helpful to train one on one with one of our reputable SmartActors coaches ( prior to your audition.  That will help to increase your confidence level and strengthen your skills during the audition process.
