I get this question a lot! I mean...a lot! Being a former acting coach myself, I have definitely learned that almost anyone feels they can teach acting, even after only a few years in the business. And it's a bit annoying. Google the Dunning-Kruger Effect. The market in most major cities is saturated with acting classes. I had a friend once travel from Canada to New York to attend a two month acting class because a few famous actors took the same class. I tried to warn her that I'm sure those famous actors went through every acting class they could get their hands on which means every acting coach could claim so-and-so was trained under them. So just because some famous actor took an acting class, it's really not evidence that the class is any good unless they still publicly endorse it. So how do you know if the acting class is worth it? Here is a cheat sheet that will help you out:
At the end of the day, the answer is YES of course acting classes are worth it? Where's my evidence? Read the back of famous acting books and see who recommends them? You'll find it's from famous actors! The reason being is they didn't just once take a few acting classes. Many who are still winning Oscars, constantly take private lessons. Yes, even Meryl Streep. Look up one of her acting coaches Harold Guskin. David Mamet's book "True and False," was recommended by Anthony Hopkins. I could go on, trust me. So you should take acting classes, BUT, do your research first because there are too many out there who believe they can teach because they have a few years of training under their belt, google "Dunning-Kruger effect." I know I said that up at the top, but trust me, it's important to know 'cause this industry is filled with people who may have been working for ten years, but they've really only been working one year...ten times. They will waste your time or even worse, send you down a long, dark path with the wrong information and it will take another acting teacher a lot of work to clean up the bad habits you were taught.
